Ah, yes, you are right: I forgot the ``system headers'' trick of GCC.
Sorry.

But gettext is not the only package that includes the system include
directory explicitly.  Readline is another (and so GDB is affected
too, and probably so is Bash).

It would be nice if people who port packages won't have to use such
kludgey solutions.  For GDB, I simply ignored the warning, but I don't
like that.

More importantly, the more serious problem is that programs compiled
with and without -fno-builtin might behave differently.  That kind of
subtle differences could cost someone many hours of futile debugging.
