The port itself builds fine on:

• 11.4 amd64
• 11.4 i386
• 12.2 aarch64
• 12.2 amd64
• 12.2 i386
• 13.0 amd64
• 13.0 i386
• 14.0 aarch64
• 14.0 amd64
• 14.0 armv6
• 14.0 armv7
• 14.0 i386
• gcc10 (mimic powerpc64 on FreeBSD < 13)
• gcc11

Whoops, the x11/foot failure actually is a bug in epoll-shim. I messed up the "fcntl" dispatch logic a bit, is actually was intended to compile warning free on all C99 conforming compilers. A fix for epoll-shim is incoming.

[jan.kokemueller_gmail.com]

With epoll-shim 0.0.20210418 the warning in x11/foot should hopefully be fixed.

• Update
• Drop x11/foot workaround

All testing redone.
