Tue Jun 9 13:50:09 1998 Thomas Bushnell, n/BSG <tb@mit.edu>
* cthreads.c (cthread_fork_prepare): Don't call
malloc_fork_prepare since we are no longer providing our own
malloc in this library.
(cthread_fork_parent): Likewise, for malloc_fork_parent.
(cthread_fork_child): Likewize, for malloc_fork_child.
Wed Aug 20 15:39:44 1997 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>
* cthreads.c (cthread_body): Wire self before calling user work
function. This way all cthreads will be wired, which the ports
library (and hurd_thread_cancel, etc.) depend on.
Fri Aug 8 13:21:17 1997 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>
* Makefile (SRCS): Delete malloc.c; libc now has a thread safe
malloc.
(malloc.c): Delete file.
Mon Jun 9 21:18:46 1997 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>
* cthreads.c (cthread_fork): Delete debugging oddity that crept
into source.
Thu Apr 3 20:29:27 1997 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>

Tue Feb 18 16:28:36 1997 Miles Bader <miles@gnu.ai.mit.edu>
* i386/thread.c (cproc_setup): Correctly leave space at top of
stack for GNU per-thread variables.
Mon Nov 18 16:36:56 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>
* cprocs.c (cproc_create): Cast CHILD in assignment.

Wed Sep 4 09:06:09 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>

asm_syntax.
Thu Aug 29 12:50:37 1996 Thomas Bushnell, n/BSG <thomas@gnu.ai.mit.edu>
* i386/csw.S: Include <mach/i386/asm.h> instead of <i386/asm.h>.

Thu May 9 11:13:42 1996 Michael I. Bushnell, p/BSG <mib@gnu.ai.mit.edu>
* Makefile (installhdrs, installhdrsubdir): Install headers using
the generic technique, now that installhdrsubdir is available.
* rwlock.h: If _RWLOCK_DEFINE_FUNCTIONS is defined, then clear
_EXTERN_INLINE, but *after* header files have been included.
* rwlock.c (_RWLOCK_DEFINE_FUNCTIONS): New macro; use in place of
clearing _EXTERN_INLINE, which conflicts with machine-sp.h.
Sat May 4 05:33:57 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* cthreads.h [lint] (NEVER): Spurious global variable removed.

new size request fits in the old one and doesn't waste any space.
Only free the old block if we successfully got a new one.
Wed Mar 6 18:05:57 1996 Miles Bader <miles@gnu.ai.mit.edu>
* malloc.c [MCHECK] (struct header): New type.
(union header): Only define if !MCHECK.
(HEADER_SIZE, HEADER_NEXT, HEADER_FREE, HEADER_CHECK): New macros.
[MCHECK] (MIN_SIZE): Add correct definition for this case.
(more_memory, malloc, free, realloc): Use above macros, and add
appropiate checks & frobs in MCHECK case.
Wed Jan 31 20:05:57 1996 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* cancel-cond.c: Add assert to check for signal bug.
Wed Jan 24 13:38:11 1996 Roland McGrath <roland@churchy.gnu.ai.mit.edu>

Bushnell will be shot.
Fri Sep 22 13:51:22 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* cprocs.c: Include hurd/threadvar.h.
Sat Sep 16 13:42:02 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* Makefile (CPPFLAGS): Variable removed.
(lndist-i386-files): Use $(top_srcdir) in place of $(srcdir).
