Yep, that is the grandparent of my fork; it has at least one group in between.
I am forking from David Flamand / gcc6809 * GitLab with possible changes from other fork that uses GCC 4.6.4 as their base.
Edit: I am trying to build under MSys2 MinGW64 32 bit GCC and failing in building newlib or GCC and decided to fork my work to help anyone else trying something similar.
