<opinion>
but what if someone *wants* to compile the win32 version with gcc?
what's wrong with that?

the problem is that these applications of which you speak can't
tell the difference between win32-only, unix-only and unix-plus-win32.
they really should (sooner or later).

so a better plan is to make the appropriate changes to each of these
applications and send patches back to their authors.

what you suggest condones/supports ignorance of the cygwin32 platform
on the part of software developers. who does that serve?
