mingw fixes:
1) mingw needs an #include to have access to mkdir. 2) It needs to always #include port.h (this is an identical bit of code, in configure.ac, that I have in other opensource projects for mingw support.) 3) I moved some code from port.cc to port.h, so I didn't have to add logic to link in port.cc for mingw. Last change before new release! (*knock on wood*) Submitting TBR so I can get the release out today. This isn't exactly a trivial change, so I'm chary to submit TBR, but it's pretty isolated to windows and mingw, and I've tested on those platforms to make sure they compile and all tests pass.
