As summary says fontforge will fail to build when compiled against python 3.8 The redhat bugzilla could be a good starting point (1728058) /bin/sh ../libtool --tag=CC --mode=compile

Thank you for the report. Please recompile and *attach* the logfiles and paste the emerge info as described on https://wiki.gentoo.org/wiki/Attach_the_logs_to_the_bug_ticket We need to have all information at hand before ticket assignment, so that the maintainer can look after it in one session with minimal number of callbacks.
Commenting here after #gentoo-python was pinged looks like the build system needs to be updated to remove "-Werror=implicit-function-declaration" and "-Werror=int-conversion", generally "-Werror" should be patched out. Why are python3.8 bugs being reported for packages that do not have python3_8 in PYTHON_COMPAT? That generally means they aren't expected to work, or have not been tested.
Werror for specific warnings is fine, and should not be patched out. And I welcome the python3.8 testing.
Meanwhile media-gfx/fontforge-20200314 went stable including python3_8 support. IMHO this bug should be closed.
