Fred Fish 7f12eb53ca * 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.

Jason Molenda 89097c5bc5 * configure.in: add check for stddef.h
* mmalloc.h: include stddef.h if HAVE_STDDEF_H is defined.

Jason Molenda c93a17b7ab * configure.in: add AC_HEADER_STDC check.
* mmalloc.h: check if STDC_HEADERS instead of __STDC__.

        * mmprivate.h: check if STDC_HEADERS instead of __STDC__.

This change is necessary to build under AIX 3.2.5 w/ cc after Stan's
Oct 24 change.  I'm not convinced that changing mmalloc.h in this way
is such a good thing--if a directory that doesn't use autoconf (or one
that DOES use autoconf but doesn't put all the defines on the command
line), and it includes mmalloc.h, the right thing won't happen.

I believe gdb is the only directory which uses mmalloc, though, so
it should be OK.

Fred Fish fa128a27ab Only redefine size_t and CHAR_BIT if they are not already defined. 1992-04-08 05:17:56 +00:00
Fred Fish f73b6c4867 Get rid of the other half of the ugly kludge as well... 1992-04-07 03:54:54 +00:00
Fred Fish aafba48f94 Get rid of include of <stdlib.h>, which is not guaranteed to be present
even when __STDC__ is defined.  This also causes the ugly malloc/realloc/etc
kludge to go away.

Fred Fish 9640d88754 Add kludge to work around broken <stdlib.h> in gcc installation on Suns.
Fixup some comments in mcalloc, mfree, mmalloc, and mrealloc.
