- (bal) Reorder. Move all bsd-*, fake-*, next-*, and cygwin* stuff to
openbsd-compat/. And resolve all ./configure and Makefile.in issues
assocated.
Logic:
* All OpenBSD functions should have the same filename as in the OpenBSD
tree
* All 'home brew' functions have bsd-* infront of them.
* All 'not really implemented' functions have fake-* infront of them.
