4241 dnl On AIX Emacs uses the gmalloc.c malloc implementation. But given
4242 dnl the way this system works, libc functions that return malloced
4243 dnl memory use the libc malloc implementation. Calling xfree or
4244 dnl xrealloc on the results of such functions results in a crash.
4246 dnl One solution for this could be to define SYSTEM_MALLOC in configure,
4247 dnl but that does not currently work on this system.
4249 dnl It is possible to completely override the malloc implementation on
4250 dnl AIX, but that involves putting the malloc functions in a shared
4251 dnl library and setting the MALLOCTYPE environment variable to point to
4252 dnl that shared library.
4254 dnl Emacs currently calls xrealloc on the results of get_current_dir name,
4255 dnl to avoid a crash just use the Emacs implementation for that function.

5364 dnl Since we get a doc/emacs directory generated anyway, for the Makefile,
5365 dnl it is not quite the same. But we are generating in $srcdir.

5373 dnl which is probably harmless, but confusing (in out-of-tree builds).
