Fix / suppress warnings for clang+mingw

Browse source 
Switch attribute error to attribute unavailable, which apparently works
since it then broke the build :-/

Suppress unused parameter warnings. They aren't that useful for windows
functions that are just #ifndef WIN32. This is marked as a global cflag,
but something is overriding that with the clang+mingw changes, and it's
not actually that hard to suppress or fix where necessary.
