<bugzilla at FreeBSD.org>'s request for maintainer-feedback to mono at FreeBSD.org:
Bug 198404: lang/mono (mono 3.12.1) does not build on i386
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=198404



--- Description ---
The recent update to mono 3.12.1 does fail on 10.1-STABLE / i386 due to type
ucontext_t being undefined. The same version does build ok on amd64.

Log sample where the build starts to get wrong:
