Eeeeekkkkkk!!!!! Arrrrrggggghhhhh!!!!
You're relying on the fact that System.Info.os is wrong to do a conditional test.
It's not a complete accident: we did envisage that making a distinction between a compiler that produces binaries via MinGW's gcc and a hypothetical compiler that produces binaries via MS's C compiler might be important, so we made System.Info.os include that distinction. Similarly it would have the value "cygwin" for a cygwin build. Nevertheless, you could persuade me that this is less than useful if you just want to know if the OS is Windows. But then perhaps there should be some other System.Info entity with more information about the OS? Cheers, Simon
