I can compile gettext-0.13.1 with these CFLAGS (except -Wendif-labels
which my gcc doesn't understand) without problems.

But on glibc systems stpcpy and mempcpy are also defined as functions:
$ nm --dynamic /lib/libc.so.6 | grep ' stpcpy'
0007ab00 W stpcpy
$ nm --dynamic /lib/libc.so.6 | grep ' mempcpy'
0007a880 W mempcpy

To me it looks more like your configure file doesn't test for stpcpy().
Have you verified that you configure.{ac,in} invokes AM_GNU_GETTEXT and
that the implementation of AM_GNU_GETTEXT you are using in aclocal.m4
matches the version of the intl library ("cat intl/VERSION")?
