[PATCH] More portability fixes

[Dan Fandrich]

Attached are some more patches in the same vein as my last batch,
primarily to improve portability.  A few of the patches do increase the code
size slightly, so to make them more palateable, I'm including an unrelated
patch to eliminate some redundant code and decrease the total binary size.
Finally, for completeness, the last, unapplied patch from my previous
set is also included.
