Batch of tiny changes for MSVC compiles.

Most of these fall into the category:
- don't use struct to refer to a class, and vice versa
- msvc doesn't like unistd.h or dirent.h

Doesn't fix all the struct/class problems; I think I'll silence
those for now and move on because it's not all that important.

Tested on OS X.
