	presence of a suitable declaration in the system headers.
	* configure: Regenerated.

1999-01-04  Jason Molenda  (jsm@bugshack.cygnus.com)

	* configure.in: Requires autoconf 2.12.1 or higher.
	* configure: Regenerated.

1998-07-24  Jim Blandy  <jimb@zwingli.cygnus.com>

	* mcalloc.c: #include <sys/types.h> before <string.h>.  HP/UX 11.0

        * mmalloc.h: Include sys/types.h and stdio.h #ifndef HAVE_STDDEF_H.
        * mmprivate.h: Do not handle HAVE_STDDEF_H here, since we include
        mmalloc.h.

Tue Mar 24 17:07:02 1998  Stu Grossman  <grossman@bhuna.cygnus.co.uk>

	* Makefile.in:  Get SHELL from configure.

        * mmalloc/detach.c: Do not include fcntl.h.

Thu Aug 28 13:15:07 1997  Andrew Cagney  <cagney@b1.cygnus.com>

 	returning it.  Makes debugging much easier at negligible cost.

Tue Feb  4 16:30:59 1997  Ian Lance Taylor  <ian@cygnus.com>

	* mvalloc.c (cache_pagesize): Rename from pagesize, so that if we
	are building mm.o, it does not conflict with the variable of the
	same name in mmap-sup.c.

Sat Dec 28 12:48:32 1996  Fred Fish  <fnf@cygnus.com>

	* Makefile.in (mm.o): New target that combines all the functions
	into a single object module.  This avoids client programs picking
 	up part of the allocation routines from mmalloc and part from libc,
 	which can lead to undefined behavior.
	(CFILES): Add mm.c
	(TARGETOBJS): Define to be either the individual objects or the
	single combined object.
	(TARGETLIB): Create the archive using TARGETOBJS.
	* mm.c: New file that simply #includes the other source C files.

Wed Sep  4 18:02:45 1996  Stu Grossman  (grossman@critters.cygnus.com)

	* configure configure.in:  Don't default CC to cc.  It causes problems
	when starting a compile in the mmalloc directory.

Wed Jul 24 00:53:34 1996  Fred Fish  <fnf@cygnus.com>

	* mmalloc.h (mmalloc_findbase): Add prototype.

	* mmap-sup.c (mmalloc_findbase): Change to not require /dev/zero
	if MMAP_ANONYMOUS is available.

Wed Jul 10 23:53:42 1996  Fred Fish  <fnf@cygnus.com>

	* detach.c (mmalloc_detach): Fix bug in computation of negative
	brk value.
	* mmcheck.c (mmcheckf): Renamed from mmcheck and new FORCE argument
	added.  Replaced hack that always allowed checking routines to be
 	installed and enforce restriction that they have to be installed
	prior to allocating any memory on the used heap or the FORCE argument
	has to be non-NULL.
	(mmcheck): New function that calls mmcheckf with FORCE set to zero,
	for backwards compatibility.
	* mmalloc.c (malloc): Store result in local variable before
	returning it.  Makes debugging much easier at negligible cost.
	* mmalloc.h (mmcheckf): Declare.
	* attach.c (reuse): Call mmcheckf rather than mmcheck.
	* mmap-sup.c (__mmalloc_mmap_morecore): Improve to allow mmap
	to select a base mapping address if none is otherwise given.
	(mmalloc_findbase): New function that user can call to find
	an available mapping address of a given size.

	* Makefile.in (bindir, libdir, datadir, mandir, infodir, includedir):
	Use autoconf-set values.
	(docdir): Removed.
	* configure.in (AC_PREREQ): autoconf 2.5 or higher.

	From H.J. Lu (hjl@gnu.ai.mit.edu):
	* mvalloc.c (valloc): new.
	* mmemalign.c: Allocate (SIZE + ALIGNMENT - 1) and then trim
	if possible.
	(memalign): don't put the node on the _aligned_blocks list more
 	than once.

Mon Nov 20 12:04:32 1995  Fred Fish  <fnf@cygnus.com>

	* Makefile.in (OFILES): Make objects depend upon Makefile,
	since Makefile sets DEFS which can definitely affect how
	objects are to be compiled.
