- remove unnecessary #includes (I think a couple of redundant ones remain)
- excise some unused code (#if 0'd out - don't want to nuke it yet)
- fix problems with "make depend" - some macros were screwing it up
- get rid of some static local variables
There still seems to be a small reentrancy problem somewhere.
