Not a definitive answer but I would expect 4.8.x to build cleanly enough.
At the other extreme, I can report complete build failures of 4.3 (for
AVR-Ada) with compilers of the 4.5 era onwards, because they stopped
accepting negative enums (!!!) in the C sources which were present in the
earlier compilers.
So I would place 4.4 as a lower bound of what *might* build and 4.8 as a
likely upper bound.
Between those, you probably have to bisect...
