It for sure is if you don't even provide the precise commands and logs of a failed run...

FWIW, I can cross compile postgres from linux to 32bit windows without an issue. If you really just need a 32bit libpq, that might actually be easier.

You'd need a windows openssl to actually have a useful libpq, but that should be fairly simple.
There are two warnings that I think point to us doing something wrong, but they're not affecting libpq:
