The current build system is broken. I've attached the patch that does the
following
1) Cleaned up .dsw file to remove links to deleted projects.
2) Added missing include to "include/portable.nt"
3) Added some missing .c files to project files
4) Ifdefed out calls to geteuid()/getegid(), not implemented on Windows
5) Removes some unused varibles
