Your package build-depends on GCC 14, which won't be shipped in
forky. Please use the default GCC if possible (currently 15) instead
of hardcoding a specific version, or alternatively, use a newer version
(15 or 16).

I see this was recently fixed for GCC 13, which is an improvement (thanks!),
but ideally this should move forward to GCC 15 or 16.

Cheers,
