Thanks for all the work in improving static checking for Cygwin builds.
I just now checked the attached patch into master, which I hope improves
on it. I tested it on Fedora (both with and without window systems).

Thanks.  That's a big improvement.

I had one problem with the recent changes, in that they suppressed all
warnings about jumps over AUTO_STRING calls. That's pretty drastic, as
the warnings are typically useful, so the attached patch reverts that.
Can you let me know which call needs the warning suppressed in the
Cygwin-specific code in the new master? I can suggest something which
disables the warning just for that call.

It's in line 7057 of w32fns.c. I see that you fixed a similar warning in xfns.c in commit e0400b7 by moving the AUTO_STRING call. I've just done the same thing in commit bbc58fe.
