No, it will most likely *fix* it.

I've already waited most of a year for this to be considered, and
nothing has yet to be done; we're not interested in waiting another year
or more for packages to build OOTB.

It's prone to errors or misconceptions, particularly if the default
would be off (as you seem to imply).

Bottom line: we insist that the CMake in the Cygwin distro not define
WIN32.  If you're prepared to handle that upstream now, great.  If not,
we will need to ship a patched version until this issue is rectified.
How do you wish to proceed?
