Please branch and build unifdef in epel9. If you do not wish to maintain unifdef in epel9, or do not think you will be able to do this in a timely manner, I would be happy to be a co-maintainer of the package (FAS dherrera); please add me through https://src.fedoraproject.org/rpms/unifdef/adduser
This package has changed maintainer in Fedora. Reassigning to the new maintainer of this component.
For EL9, unifdef is in the CRB (CodeReady Linux Builder) repository. It’s therefore not eligible for EPEL9, and you’ll need to enable CRB instead.
