The only explanation that I can see is that you ran both builds (first without
--with-libexpat-prefix, then with --with-libexpat-prefix) in the same directory
and did not run "make distclean" before the second run of ./configure.
As a consequence, the "make" after the second ./configure did not rebuild
anything. Your change to x-glade.c then forced a rebuild of x-glade.o and of
xgettext, taking into account the HAVE_LIBEXPAT setting.

So, always do a "make distclean" before configuring a package that was
partially built before in the same directory.
