But the issue Matthias is interested in is the freeness of lack thereof of the FDL and whether it's an issue for the GPC documentation with regards to Debian usage. that's not an issue I can answer, hopefully others know the answer.
well, the original question was, which "invariant section" statement the GPC manual pages have.
another issue are the "Front-Cover Texts" and the "Back-Cover Texts". I've never seen these texts from GPC in, i.e. a GNU/Linux distribution, so this is not only Debian related ...
