At first I had flint-3.1.0 from Gentoo portage. Got same errors and build

These errors,
local/include/flint/nmod_mpoly_factor.h:366:49: error: expected ')' before
'__extension__'
arise from flint's use of the variable name "I" in a few places. C99
technically forbids that IIRC. Our flint-3.1.3_p1 package (but no
earlier versions) contain a patch from Dima to fix the issue.
We were expecting people to hit this with gcc-14 which is still
unstable, but I guess some of the patches that have been backported to
your 13.3.1_p20240614 trigger it. I've filed a stabilization request
for flint-3.1.3_p1 to get ahead of the problem.
Yes, that weirded me out in
https://github.com/cschwan/sage-on-gentoo/issues/789
But not everyone with a gcc-13.3.x compiler is affected, so there maybe
something more subtle at play. Maybe a compiler use flag?
