3610 dnl On AIX Emacs uses the gmalloc.c malloc implementation. But given
3611 dnl the way this system works, libc functions that return malloced
3612 dnl memory use the libc malloc implementation. Calling xfree or

3615 dnl One solution for this could be to define SYSTEM_MALLOC in configure,
3616 dnl but that does not currently work on this system.
3618 dnl It is possible to completely override the malloc implementation on
