As far as I know, everything you say above is correct; the documentation
you're generating is GPL'd. (IANAL, of course.)
In any case, that wasn't what the discussion with RMS was about. It was
about two things:
1. What license should "manuals" have?
The FSF wants them to be GFDL. However, RMS agreed that it's OK for
"cross-reference" information (as opposed to "manuals"), auto-generated
from source code, such as the documentation you're generating with
doxygen to be GPL'd. So, the procedure you're using is fine, not just
from a "is this legal" point of view, but also from an FSF policy point
2. Can we move GPL'd code into GFDL'd manuals, or copy text from GFDL's
manuals into GPL'd code, or auto-generated GFDL's manuals from GPL'd code?
This got complicated; see previous postings. But, it's not relevant to
your question, since you're not trying to do that.
