Dear Maintainer,
while working on the pyfai packages, I got an FTBFS due to gcc-14.
like this

It seems that gcc-14 considere that incompatible-pointer-types is now an error.
The workaround proposed by cython is for now to retrograde the erroor int a
warning with this flag
This is now an error in GCC 14: gcc-mirror/gcc@9715c54 .
A temporary workaround is to set CFLAGS="${CFLAGS}
-Wno-error=incompatible-pointer-types".
