Supporting alternative toolchains on Windows

[Julian Waters]

Hi all,

How feasible would it be/much effort would it require to support compiling
with alternate toolchains on Windows besides Visual C++ (like the Windows
ports of clang and gcc) if we restrict the allowed toolchains to only those
that link against the ucrt? (Toolchains linking against the dated msvcrt
would present too many issues to work with)

best regards,
Julian
