Support building OpenJDK on Windows using MSYS2 and MinGW-w64 GCC?

[Philip Race]

Some issues I see here are that
- the code has lots of things like #ifdef _MSC_VER .. fixable perhaps, 
but ..
- the Windows SDK which includes the compiler is needed anyway
- no one is likely to maintain this ..
- Oracle is unlikely to use this for its own builds.

So probably not something Oracle would invest in and not sure who would
do it and keep it working .. whilst ensuring the VC code is still needed.
