The GCC development branch which will become GCC 13 is now in
bugfixing mode (Stage 3) until the end of Jan 15th.
As usual the first weeks of Stage 3 are used to feature patches
posted late during Stage 1. At some point unreviewed features
need to be postponed for the next Stage 1.

Note using cygwin (or mingw for that) might make GCC development more
painful than necessary. It might be
that using a WSL2 based setup is easier if you're stuck to a Windows
host. Using Linux in a virtual machine
might be another option of course.
