How can we test for sigsetjmp working or not working in a cross-build
environment, though.

I have changed opinions on whether sigsetjmp should work in cygwin about
five times today.  After spending some time looking at the code, I have
to confess that it seems like it should work ok to me.  That's my
current opinion, anyway.

I'd like to understand the kind of problems that Keith is seeing.  Maybe
there is something that can be done to the sigsetjmp/siglongjmp macros
to fix this problem in gdb so that we don't have to say "upgrade cygwin".

I'm very interested in fixing cygwin, though, of course.
