	* use scandir, alphasort and ftw from glibc 1.05.

	* use <sys/cdefs.h> from glibc 1.05 to replace <traditional.h>.

	* system call idle was added.

	* the floating point output bugs, `%-xxx' stuff, were
	  fixed.

	* there was a new structure for compiler:
	  different versions of library, i.e., static, jump table
	  and classic shared library, would be in the same directory.
	  static verion would be libfoo.a. jump table version would
	  be libfoo.sa and classic version would be libfoo.ca. `ld'
	  would search for the jump table library by default. you can
	  overwrite it by adding -static or -nojump to `ld' or 'gcc'.
	  jump table and classic verions are not compatible with
	  each other. and the static library is used as the last
	  resort.

	* strcmp, strncmp and memcpy were fixed for unsigned char.

	* sun rpc 4.0 was in.

	* the GNU C library 1.05 was used.

	* use `xchg' in system calls.


Fri Sep 11 13:29:05 1992  H.J. Lu  (hlu@poly2)

	* rearrange the file structures of gcc. separate compiler from
	  libraries and header files. Here is the new structure:

	  1. static libraries are in /usr/lib.
	  2. jump table version of shared library stubs are in
	     /usr/lib/shlib/jump.
	  3. classic version of shared library stubs are in
	     /usr/lib/shlib/nojump
	  4. default for gcc is jump table. the other options are -nojump
	     and -static. -g and -pg will use the corresponding static
	     libraries.

        * shared images are in a separate package.

	* from this release on, the gcc will follow the FSF naming. the
	  libraries will be named after jump table version number. the
	  current versions are gcc 2.2.2d, the Linux C library 4.1 and
	  the Linux math library 4.0. the Linux math library won't change
	  with the minor version number. so for all the version y.xxx's,
	  there is only one release of math library, version `y.0'.

	* file list for gcc 2.2.2d, libc 4.1 and libm 4.0:

	  1. 222d7.TZ
	     gcc 2.2.2d linked with jump table 4.1. it has gcc, cc1,
	     cc1plus and cpp. it also has version dependent header
	     files. unpack it under /.

	  2. lib41.tar
	     static libraries and shared library stubs. it has lib-4.1.TZ
	     and lib-4.1.sh. run lib-4.1.sh will install lib-4.1.TZ. do
	     
	     lib-4.1.sh

	     you have to have a real sh to run it. This script is used to
	     install the math library, soft or hard.

	  3. inc-4.1.TZ
	     header files for lib 4.1. unpack it under /. You have to make
	     two symbolic links. one from include/linux of kernel source
	     to /usr/include/linux, another from include/asm of kernel
	     source to /usr/include/asm. There is a file,
	     /usr/include/linux/const.h. You have to move it to
	     include/linux of kernel source before you make symbolic link.
	     unpack it under /.

	  4. jump41.tar
	     shared images for jump table 4.1. it has jump-4.1.TZ and
	     jump-4.1.sh. do

	     jump-4.1.sh

	     to install jump-4.1.TZ. this script is used to install the
	     shared math image, soft or hard.

	  5. libdp-4.1.TZ
	     libc_p.a and libg.a. unpack it under /.

	  6. jump-src-4.1.TZ
	     scripts for build jump table 4.1. almost no documentations.
	     contributions are welcome.

	  7. lib-src-4.1.TZ
	     source code for the Linux C library 4.1.

        * the install procedures are minimal. it didn't do much file
	  permission fixing. fix them when you find they are wrong.

	* this release contains no new binaries for gcc, cc1, cc1plus or
	  cpp. only things changed are in libraries.

Mon Sep  7 13:44:09 1992  H.J. Lu  (hlu@poly2)

	* change to jump table 4.1

	* add prefix __ to header files.

	* use strftime from shellutils 1.7 to replace the one from
	  glibc.a 1.03.	

Sat Sep  5 16:57:21 1992  H.J. Lu  (hlu@poly2)

	* swapoff, wait4 (real one, need 0.97 pl3 or above) are
	  added.

	* vm86 () and <sys/vm86.h> are added.

Fri Sep  4 17:31:44 1992  H.J. Lu  (hlu@meriadoc)

	* change jump table to 4.0. Add __brk_addr to global data.
	  fix streambuf static member, _list_all.

Wed Sep  2 13:01:59 1992  H.J. Lu  (hlu@poly2)

	* __overflow () and __underflow () are moved into a separate file
	  to facilitate the implementation of jump table.

	* getdtablesize () returns OPEN_MAX.

	* GNU regex 0.9 is used.

	* file lock in gdbm is changed for real thing in 0.97 pl 2.

	* ntol? () and hton? () netinet/in.h are fixed. 

Thu Aug 27 00:12:10 1992  H.J. Lu  (hlu@yoda)

	* regex (version 0.9) from shellutiles-1.7 is used.

	* bsd style signal () is added in <signal.h>. define _USE_BSD_SIGNAL
	  to use it.

	* sigblock and sigpause () are added.

	* ftw () is added. It is untested. It uses seekdir and telldir ().
	  I am afraid it may not work with VFS.

Wed Aug 26 00:17:33 1992  H.J. Lu  (hlu@fili)

	* scandir () and alphasort () are added.

	* killpg () is added to <signa.h>.

Sun Aug 23 14:49:23 1992  H.J. Lu  (hlu@poly2)

	* some files are changed for the new shared image scheme.

	* you have to have 0.97 pl 2 or above to use it.

	* define WTMP_FILENAME and UTMP_FILENAME as WTMP_FILE and
	  UTMP_FILE in  <utmp.h>.

Sat Aug 22 10:57:11 1992  H.J. Lu  (hlu@luke)

	* fix re_comp ("").

	* setfileno () is added to stdio. don't use it unless you have to.

	* use POSIX signals in curses, ./posix/system.c and
	  ./iostream/procbuf.C
	  

----------------Start to Use ChangeLog------------------

Thu Aug 12 1992 

	* gcc-2.2.2d
	You need to have the header files from virgin Linux kernel 0.97 patch 1 
	or above on line to use this release.
	The source codes for gcc itself is unchanged from 2.2.2, but it was
	recompiled for new kernel. And lots of bugs are fixed.

	I am trying to make the Linux C library to be POSIX.1 compliant. I
	cleared up the header files and some library functions.
	1. <limits.h> and <unistd.h> are fixed. (in 2.2.2dmisc.tar.Z)
	2. <time.h> is fixed, remove __tzname_max (). (in 0.97pl1inc.tar.Z)
	3. posix/sysconf.c. (the shared image is compiled with old one. I
	   don't think it will matter too much. this will be fixed in the
	   next release.)
	4. time/Makefile (remove tzname.o)

	There are some problems with pathconf()/fpathconf(). We need a new
	sys call to get info about the filesystem. Someone mentioned
	vfsstat (). It may be a good idea. To be compliance with POSIX.1, we
	need
	1. LINK_MAX
	2. MAX_CANON
	3. NAME_MAX
	4. PATH_MAX
	5. PIPE_BUF
	6. _POSIX_CHOWN_RESTRICTED
	7. _POSIX_NO_TRUNC
	8. _POSIX_VDISABLE
	Some of them may change for different filesystems. Some don't. Some may
	do in the future.

	The installation procedure is changed. Please read README first.

	The new correct setjmp/longjmp are not compatible with gcc 2.2.2. If
	your code uses them, please recompile it with gcc 2.2.2d. And
	DO NOT USE setjmp/longjmp WITH THE SHARED X386 v1.1, WAIT FOR v2.0.

	The following bugs in libraries are fixed.
	1. div/ldiv.
	2. setjmp/longjmp.
	3. crt0.o/gcrt0.o. 387 control word is changed to 0x1272. No overflow
	   exception.
	4. floating point format errors are fixed.
	5. minor bug in mntent.c.
	6. popen.o is fixed in libg.a.
	7. fopen ("foo", "a") will seek to the end of file.
	8. printf ("%10.2f\n", 10.0);
	9. libg++.a 2.2 is used.
	10. libinet.a is folded into libc.a. All the data bases are in
	    /usr/etc/inet. But you need kernel support for that. Please
	    contact "bir7@leland.stanford.edu" first.
	11. a typo in libc-linux/socket/bytedorer.c is fixed.
	12. size of args + envs for exec () is fixed.
	13. new mount for 0.97.
	14. a bug in temporary filename creation is fixed. Now it checks
	    if a process has permission to create a file in specified directory.
	15. in libhard.a, pow (0.0, 0.0) = 1.0 now.
	16. cc1/cc1plus is fixed for
	    double foo=DBL_MAX;

	The following functions are added to libraries.
	1. setpiority/getpiority.
	2. iopl.
	3. sigsetjmp/siglongjmp.
	4. cfree.

	The following changes are made to the header files.
	You won't notice the changes unless you are testing TCP/IP. If you
	are, please first contact "bir7@leland.stanford.edu". You need more
	than that.
	1. <stddef.h> is fixed.
	2. <stdlib.h> is fixed.
	3. all the header files are now compatible with gcc -traditional.
	4. strncasecmp is added to <string.h>.
	5. <sys/asy.h> is added.
	6. lots of bugs are fixed.
	7. <sys/user.h> and <a.out.h> are changed.
	8. <sys/socket.h> and <fcntl.h> are changed for TCP/IP.
	9. <sys/syslog.h> and <sgtty.h> are in for TCP/IP.
	10. lots of header files in kernel and /usr/include are fixed. 

	two dummies, <sys/reg.h> and <machine/reg.h> are added for gdb 4.6.

	The following changes are made to libraries.
	1. byte order functions for networking are written in C. Please read
	   libc-linux/socket/byteorder.c and <netinet/in.h>

	David's jump table version 2 release 2.1 is in.

Jun 27 1992
	* gcc-2.2.2 
	Please get the new binutils.tar.Z, which fixed some bugs in as 
	and gprof with some patches from Rick Sladkey at jrs@world.std.com
	I added some jumptable stubs to gcc. But I don't have the time to
	implement it. In the future, you can use jump table with -jump in
	CFLAGS.
	Libg++.a is 2.2 beta.
	This gcc will produce binaries only run safely under 0.96a patch level
	4 or above.

	The following bugs in libc.a are fixed.
	1. hard and soft math libs are fixed. some of functions are totally
	   rewritten.
	2. acosh, asinh and atanh are added to libsoft.a and math.h.
	3. open a file for read and write, then do fseek followed by fwrite
	   works now.
	4. now random () and srandom () are renamed to __random () and
	   __srandom (), respectively.
	5. the header files taken from glibc.a are fixed.
	6. the sys call mount now takes 4 args.
	7. getpagesize and getdtablesize work now.
	8. netdb.h, resolv.h, sys/uio.h, netinet.h, arpa/inet.h and
	   arpa/nameser.h are changed.
	9. Some function declarations are added to sys/socket.h in
	   0.96bp2inc.tar.Z.

	The following functions are added to libc.a.
	1. profil.
	2. libg.a is there.
	3. getdtablesize.
	4. lots of stuffs added to errno.h and string/errlist.c.
	5. some changes in string/siglist.c.
	6. dtoa.
	7. there is a new strtod, please check it out.
	8. drem.
	9. the inet library functions are in libinet.a. They are untested. Once
	   they are tested ok, they will be moved to libc.a. All the inet
	   library functions are there, except for res_xxxx, rcmd, rexec and
	   ruserpass, which require more kernel support, like F_SETOWN, FASYNC,
	   and a few network system calls.

	   There should also be a set of files in /etc for inet functions. I
	   hope Ross will provide them.

	   In this release, there is a libc_p.a compiled with "-pg" for profiling.

	   You should use "-g" for debugging and "-pg/-p" for profiling in CFLAGS
	   when you compile the source code.


Jun 16 1992 

	* gcc-2.2 based on FSF release gcc-2.2.1
	new binutils.tar.Z, which fixed some bugs in as.
	Libg++.a is 2.1
	A new structure of gcc is introduced here. All the static libs are in
	/usr/lib/gcc-lib/i386-linux/2.xxx and all the shared libs are in
	/usr/lib/gcc-lib/i386-linux/2.xxx/shared. By default, gcc will search
	/usr/lib/gcc-lib/i386-linux/2.xxx/shared first, then the static libs.
	You can turn off the shared libs with "-static".

	The following bugs in libc.a are fixed.
	1. dirent.[ch] are fixed such that static memory no longer is used in
	    readdir ().
	2. sys/dir.h sys/dirent.h are modified such that there will be a
	    warning when both of them are included. They are also compatible
	        now.
	3. __cpluscplus in fnmath.h
	4. gets () will only give a warning during linking.
	5. wait3 ().
	6. <stdio.h> is fixed. fputc, fgets and gets are no longer macros.
	7. <sys/user.h> is added in 0.96ap2inc.tar.Z.
	8. The return value of clock ticks of the old sysconf () was wrong. It
	    returned 60 instead of 100.
	9. The domain errors in the math libraries are improved.
	10. bsearch and qsort are fixed for zero element.

	The following functions are added to libc.a.

	1. accept
	2. bind
	3. bstring
	4. connect
	5. ftime
	6. fchmod
	7. fchown
	8. ftruncate
	9. getpagesize
	10. getpeername
	11. getsockname
	12. getwd
	13. ioperm
	14. itimer.
	15. listen
	16. mmap
	17. mntent.
	18. ntohs/htons
	19. ntohl/htonl
	20. psignal
	21. ptrace
	22. setenv/unsetenv
	23. socket
	24. socketpair
	25. statfs () and fstatfs ().
	26. truncate
	27. usleep
	28. vfork
	29. wait3() and wait4 ().

	Gdbm 1.5 is here for X11R5.

	popen now is based on iostream.

	I also changed the structure of header files.


May 30 1992
	* gcc-2.12c based on ss-920528 from FSF
	From this release, gcc will use the shared lib. That means you have
	to keep the shared images used by all the compilers you have.
	Now libg++.a 2.0.91 is here.

	The following bugs in gcc are fixed.
	1. "\xxx" works now.
	2. No more warning about "__FUNCTION__" stuffs.

	The following bugs in libc.a are fixed.
	1. hypot added to math.h
	2. popen is fixed by Per, Check it out.
	3. __cpluseplus in setjmp.h
	4. copy sys/dirent.h to sys/dir.h, but change dirent to direct.
	5. proto type of gdbm_open in gdbm.h
	6. Per tried to fix fseek/fread/fwrite. Check it out.

	Here is the list of the known bugs.
	1. -O won't work with getdate.c from shellutils 1.6.
	I am trying to fix the following bugs in libg++.a.
	1. Maybe Complex.o, which uses hypot.


May 27 1992
	* gcc-2.12b
	The following bugs in libc.a are fixed.
	1. types used in sigsetmask and siggetmask are now sigset_t.
	2. a minor change in sigproc.c.
	3. signal.h is changed.

	I am trying to fix the follwing bugs in libg++.a.
	1. Regex.o and String.o
	Please do this to fix the bug in libg++.a.
	/bin/rm -rf /usr/g++-include/regex.h


May 26 1992  
	* gcc-2.12	based on FSF prerelease of gcc-2.2.
	The follwing bugs in libc.a are fixed.
	1. index.
	2. sigxxxx return values should be right now.
	3. execxxx are taken from glibc.a 1.03. Please check it out.
	4. malloc in stdlib.h and malloc.h, when they are included together,
	they may cause trouble. Can I include malloc.h in stdlib.h and fix
	malloc in malloc.h?

	The following functions are added.
	1. tell (bsd)
	2. sigsetmask
	3. siggetmask
	popen now is based on iostream.

	I also changed the structure of header files. 
	Libg++.a 2.0.90 is here, which is MUCH better than the one in gcc
	2.11c. Please try this. Stdio should be less buggy. Check it out.
	To use this release, please get new binutils.tar.Z 
	which has a new gas.

May 19 1992
	* gcc-2.11c
	ldd is supported. 
	The source code of the libraries is in libc-2.11c.tar.Z. 
	There are two files:
	gcc-2.1.tar.Z, for compiler, including some tips for cross-compiling.
	shlib-2.11c.tar.Z, for building the shared libs.

May 17 1992 
	* gcc-2.11b
	1. sleep (0) is fixed.
	2. All binaries are recompiled with new gas.
	3. X11R5 is not the part of gcc 2.1 anymore.

	Please get the new binutils.tar.Z. The old one may have bugs.
