[setup patch] Fix cygwin-mode compilation.

[Max Bowsher]

It's occasionally useful to compile setup.exe linked with cygwin1.dll, to
debug a crash that occurs within msvcrt.dll.

There was a missing bit of code in mkdir.cc, and a clashing typedef in
io_stream.h.

Along the way, I bumped into a direct include of <windows.h> in our
proppage.h, and pushed it through our win32.h, where we care about windows.h
namespace pollution (min/max) which otherwise can cause libstdc++ headers
fail.

Please check the fragment I've put into mkdir.cc.
I've never actually used stat() before!

Ok to commit?

Max.
