Here are the diffs for libc_r to get it one step closer to P1003.1c
These make most of the thread/mutex/condvar structures opaque to the
user. There are three functions which have been renamed with _np
suffixes because they are extensions to P1003.1c (I did them for JAVA,
which needs to suspend/resume threads and also start threads suspended).

I've created a new header (pthread_np.h) for the non-POSIX stuff.

The egrep tags stuff in /usr/src/lib/libc_r/Makefile that I uncommented
doesn't work. I think its best to delete it. I don't think libc_r needs
tags anyway, 'cause most of the source is in libc which does have tags.

also:

Here's the first batch of man pages for the thread functions.
The diff to /usr/src/lib/libc_r/Makefile removes some stuff that was
inherited from /usr/src/lib/libc/Makefile that should only be done with
libc.

also:

I should have sent this diff with the pthread(3) man page.
It allows people to type

make -DWANT_LIBC_R world

to get libc_r built with the rest of the world. I put this in the
pthread(3) man page.  The default is still not to build libc_r.


also:
The diff attached adds a pthread(3) man page to /usr/src/share/man/man3.
The idea is that without libc_r installed, this man page will give people
enough info to know that they have to build libc_r.

95c715795a Fixed comparisons so that preposterously large (>= 0x80000000) brk values
aren't silently converted to minbrk.  This stops malloc(INT_MAX) from
dumping core.  Small values are still silently converted.  They should
be an error.  sbrk() doesn't do any range checking or conversions or
overflow checking.

Moved PIC_EPILOGUE invocation to a more natural place where it
obviously doesn't interfere with the comparison.

cbdc4399d2 Fix a bug caused by the collision of a local assembler label with another
use of the same label in a recently-introduced PIC_PROLOGUE.  This
should solve the recent core dumps from pdksh.

7f11212ef1 Fix a bogon in the pic + threadsafe version of cerror, it was missing
a PIC_EPILOGUE (leaving an extra long on the stack).

f1703dfbaa Add support to enable libc to be compiled in ELF format. (#ifdef __ELF__)
In a nutshell, this macroizes the local/global symbol scoping rules
that are different in a.out and ELF.  It also makes the i386 assembler
stubs conform to i386 PIC calling conventions - the a.out ld.so didn't
object, but the ELF one needs it as it implements PIC jumps via PLT's as
well as calls.  The a.out rtld only worked because it was accidently
snooping the grandparent calling function's return address off the stack..

This also affects the libc_r code a little, because of cpp macro nesting.

717d9cdd57 First round of changes to clean up the RCSID mess in libc:
1) Changed LIB_SCCS and SYSLIB_SCCS to LIB_RCS and SYSLIB_RCS.
2) Changed sccsid[] variables to rcsid[]
3) Moved all RCSID strings into .text
4) Converted all SCCSID's to RCS $Id$'s
5) Added missing $Id$'s after copyright.

c501fb74cf Fixed problem with returning -1 on error when the return value is a
long long. Done by plugging both eax and edx with -1. This will clobber
edx unnecessarily when the return value is only 32bit...though probably
always an okay thing to do, it could stand a better fix.
   This was the cause of gawk being broken (boy was THAT ever a subtle
bug!!!).

2ceb2ce9ee First crack at making libc work with the new make macros. It compiles on
my machine, and a simple static (genassym) and shared (sysctl) executable
both work.  Still to be done: RPCand YP merge.
