Compile error for SageMath version 9.5.rc0

The test sage setup.py test for SageMath version 9.5.rc0 (compiled from source without errors) on an up to date Manjaro Linux machine results in:

Compiling fgb_sage/_fgb_sage_modp.pyx because it changed.

Thank you for noticing this error so quickly and reporting it here. It should be fixed now. About the compilation warnings, on the other hand, I cannot do anything, but they can be ignored.

Edit: This change is backward incompatible. In case anyone comes here with an older version of Sage or Singular, checking out an older commit should work.

Thanks, it now works on two machines under the setup as described in the post.
