I can pile on another kludge to make that compile and eventully it'll
end up linking libgccjit, but the build then stops with an error that is
not so easily skipped.
So no, Cygwin is not one of the targets that libgccjit is intended to
work on yet and needs work.
Thanks for trying.
Does injecting dlfcn.h work?
