Add contributed support for building with Microsoft's compiler Thanks to Erik G <erik@6809.org> for various updates to allow building with Microsoft's compiler. These changes, in addition to some other generally good fixups from other commits, include: * move the version define to its own source file instead of as an option in Makefile. This is better anyway. * add some compatibilty stuff to lwlib This support is minimally invasive so it should continue to work. However, this is contributed code which I have no way to test.
