I'm trying to do that on wine/msys2/mingw64 (not an actual Windows installation), and there are a number of issues that need to be fixed, and I'm wondering whether I'm the first person to run into them. Quite possibly, they're specific to wine.

I think you are indeed the first one.  I use 32-bit MinGW, and for
that I have a working build of MPS (and can share the diffs if someone
wants them), but a 64-bit MinGW build of MPS will need other changes,
at least in some cases.

Right.  I wonder why they didn't use intprtr_t or somesuch to begin
with.

Where and how do you see that?
