 #undef ALIGN_DATA_RELOC
 
+/* On AIX Emacs uses the gmalloc.c malloc implementation.  But given
+   the way this system works, libc functions that return malloced
+   memory use the libc malloc implementation. Calling xfree or
+   xrealloc on the results of such functions results in a crash. 
+
+   One solution for this could be to define SYSTEM_MALLOC here, but
+   that does not currently work on this system.
+
+   It is possible to completely override the malloc implementation on
+   AIX, but that involves putting the malloc functions in a shared
+   library and setting the MALLOCTYPE environment variable to point to
+   tha shared library.
+   
+   Emacs currently calls xrealloc on the results of get_current_dir name,
+   to avoid a crash just use the Emacs implementation for that function.
