Early work for Fedora 40's Port to Modern C (https://fedoraproject.org/wiki/Changes/PortingToModernC) is complete ahead of schedule, and it would be good to avoid regressing the progress that has been made by a limited enabling of -Werror=implicit-function-declaration and -Werror=implicit-int by default (to stop regressions). This work has some dependent changes in redhat-rpm-config and some build flag refactoring. Related to: https://fedoraproject.org/wiki/Changes/GNUToolchainF39 Reproducible: Always
This bug appears to have been reported against 'rawhide' during the Fedora Linux 39 development cycle. Changing version to 39.
