4 if MMAP_ANONYMOUS is available.

10 * mmcheck.c (mmcheckf): Renamed from mmcheck and new FORCE argument
11 added. Replaced hack that always allowed checking routines to be
12 installed and enforce restriction that they have to be installed
13 prior to allocating any memory on the used heap or the FORCE argument
15 (mmcheck): New function that calls mmcheckf with FORCE set to zero,
16 for backwards compatibility.

18 returning it. Makes debugging much easier at negligible cost.

64 objects are to be compiled.

131 * configure: New file, generated with autoconf 2.3.
132 * config/{mh-go32, mh-irix, mh-ncr3000, mh-sunos4,

170 by the source files).
174 * Makefile.in (info dvi install-info): Actually make the manual.
178 * mmalloc.texi: Fix typo ("for for" -> "for").
182 * test1.c: New file which tests for bug fixed below.
183 * Makefile.in (check): Put in commands to run it (but commented out
184 because it won't work for Canadian cross).
186 * mmalloc.c (mmalloc): When extending a free block at the end of the
187 heap, check whether which block is at the end changed.
189 * Makefile.in (TAGS): make work when srcdir != objdir.
