[Vm-dev] Issue 132 in cog: Build Fails on OpenBSD. ucontext is not available

[Eliot Miranda]

Hang on.  I don't think that's the problem.  I *think* someone found out
how to install a ucontext.h for FreeBSD.   Is that the case?

(meant to post this yesterday; the draft has sat there, but it's still a
valid question)
