* 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.

#ifndef MMALLOC_H
#define MMALLOC_H 1
Add kludge to work around broken <stdlib.h> in gcc installation on Suns. Fixup some comments in mcalloc, mfree, mmalloc, and mrealloc.
1992-04-01 21:49:00 +02:00
* 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.

/* FIXME: If <stddef.h> doesn't exist, you'll need to do something
to define size_t before including this file. Like upgrading
to a system with an ANSI C environment. */
* configure.in: add check for stddef.h * mmalloc.h: include stddef.h if HAVE_STDDEF_H is defined.
