23:00:10 2016 -0800 malloc.h hygiene This attempts to future-proof Emacs a bit against possible glibc changes, by having Emacs use declarations rather than coding them up by hand. Problem noted by Florian Weimer in: https://sourceware.org/ml/libc-alpha/2016-01/msg00777.html Implement this mainly by moving malloc.h-related functions from emacs.c (which does not include ) to alloc.c (which does). * src/alloc.c (my_heap_start) [DOUG_LEA_MALLOC || GNU_LINUX]: New function. The remaining changes to this file apply only if DOUG_LEA_MALLOC. (alloc_unexec_pre, alloc_unexec_post): New functions. (malloc_initialize_hook): Use my_heap_start and alloc_unexec_post. (__MALLOC_HOOK_VOLATILE): New macro, if not already defined. (__malloc_initialize_hook): Use it.
