OK.  I've switched to cvs HEAD, and it looks like two of the three
patches are now redundant.

This small patch switches emacs to prefer the mem* functions rather
than the b* functions when they're available since at least under
GNU/Linux, the b* appear to be deprecated.  However, if this
deprecation isn't common, the following patch might not be the right
thing to do.
