OK, but why doesn't a similar problem happen with malloc and calloc? 
lib/malloc.c has "#undef malloc", and similarly for lib/calloc.c.

No, Gawk doesn't use AC_FUNC_REALLOC or Gnulib lib/realloc.c. Similarly 
for calloc and malloc.

Perhaps we should simply remove the "#ifdef malloc" section from 
lib/malloc.c, and similar for calloc and realloc.
