It is based on an older mingw environment and I am having big 
difficulties upgrading it, still in the realm of remaining on mingw 
32bit and gcc (no libobjc2)

I have been exploring the path of msys2 (although with gcc and its 
runtime, nto clang+libobjc2) too: ideally I'd like to have both 
alternatives available for the time being, but I was unable to. I have 
other big difficulties.
I can't even compile base, issues with winsock and such.

Sorry not being able to help you further, few people work on Win support 
at all.
