Well yes some of us do. I work to keep the Wine SDK compatible with
the PSDK because we have developed a MSVC backend in the ReactOS build
system and one day (God willing) I will get the ReactOS Project to use
Wine headers rather than w32api headers. As such it needs to be able
to compile applications on MSVC and gcc.

Thanks
