Well, ok. So, my 5 cents for PCH fixing. Attached patch will allow
correct path to PCH file to be printed into preprocessed source.
Currently on systems using backward slashes as path separator (e.g.
mingw) PCH path is printed with mixed "\" and "/", even more, "\"'s are
not esacaped, so later everything got confused :)

This patch uses standard gcc way to do platform dependent filename
printing via output_quoted_string() call.
