How long does building the cross-compiler from your cygport take, usually?
I could try that and let you know if just applying the patch from
https://gcc.gnu.org/viewcvs/gcc/trunk/gcc/config/i386/winnt.c?r1=232828&r2=232827&pathrev=232828
would fix matters. Not sure how many other packaging changes you'd need
to go from 5.4.0 to 6.1.0. (And 6.2 should be coming shortly.)

According to the discussion in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66655
the underlying issue may have also been a problem for cygwin targets,
but I do much less testing there as Julia relies on async IO (via a fork
of libuv) that cygwin doesn't provide.
