| <string.h> does not define NULL. Better write (void*)0 or "" instead of
NULL.
I've since fixed this in the .m4 file. But shouldn't we make the string
module guarantee that NULL and size_t are defined, as required by POSIX,
once the gnulib replacement string.h is built? Which platforms have a
broken <string.h> that fails to define NULL?
