These two patches add support for UNC paths on MinGW, i.e. paths like `\\server\foo\bar\baz.txt`. This is my first time submitting a patch to the GCC repo, so I'm not fully sure if I submitted the patch correctly.
This was tested on x86_64-w64-mingw32. I'll try to look at the fs-operations on UNC paths after this patch, since some of them (like fs::canonical) break with UNC paths.
