A first step would be teaching gcc to not append .exe.  Many configure
scripts (certainly almost all scripts based on autoconf) determine
$(EXEEXT) based on gcc behavior, and will just do the right thing
throughout the rest of the build with $(EXEEXT) empty (as evidenced by
their behavior on Linux).

But even with that gcc change, we'd have to keep .exe magic in
cygwin1.dll until everything in the distro has been rebuilt without an
.exe suffix.

However, I'm starting to like the idea, if we can get buy-in from the
gcc packager.  Dave?

Meanwhile, the (as-yet-pending) cross-compiler to build mingw
executables _should_ continue to output .exe suffix, and anything trying
to still be portable to mingw will have to be even more careful to use
$(EXEEXT) properly because cygwin would no longer be helping out (but
then again, that's exactly the situation you face when using wine, since
Linux is not helping out).
