Hi,

Yes, it doesn't work, because it requires cl.exe to be used in a specific way
(only a single input file, specific output file naming). Which would require a
decent amount of changes to src/tools/msvc. I think it's more realistic with
meson etc.

I don't think it's really usable for what we need. But it's hard to tell.

That's relatively easily solvable by using a different debug format IIRC (/Z7
or such).
