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.

aacd7f348e Be smarter about handling overlapped copies and only go backwards if it
is really necessary. Going backwards on a P6 is much slower than forwards
and it's a little slower on a P5. Also moved the count mask and 'std'
down a few lines - it's a couple percent faster this way on a P5.

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.

75b6d64b84 fixunsdfsi.S:
Embalm.  Rewrite to do things much the same as gcc-2: use fistpq for speed
and elegance, and mishandle overflow consistently.  __fixunsdfsi() is no
longer called by gcc.

7e20f2848c Go back to Bruce's fix with a minor change that will allow a NULL string
pointer if len is 0. I should have looked at the revision history - I would
have found that Bruce already fixed the bug with len=0 over a month ago.
Whoever said that the bug was in 2.0 was wrong.

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.
