ports/devel/gettext/Portfile contains:

configure.cppflags      -no-cpp-precomp

Commentting this line out fixes the issue.

[jmroot (Joshua Root)]

Building ports with arbitrary compilers is of course totally unsupported, but -no-cpp-precomp might as well go away since it has done nothing since something like gcc 3.1.

[ryandesign (Ryan Carsten Schmidt)]

-no-cpp-precomp was removed in [e4160136a99bcfc25938e5afbb06e3f77c455871/macports-ports].
