--- Comment #3 from Roland Illig <roland.illig at gmx dot de> --- Would it be possible to teach exgettext that inside the _(...), the only allowed tokens are string literals, and maybe the PRIU64 constants? There's probably some more tokens that I just forgot, but a test run over the GCC source should reveal most of them.
