Thanks, very interesting. Though what I meant with "the above" was
actually the Cython case :-).

To me this all sounds as if packages using Cython in the build process
*should* use Build-Using: cython then. Cython certainly doesn't have the
same license exception that gcc has, and there also isn't much of a
precedence (compared to eglibc).
