We could move these macros to a new include file, and have it
be included only by .c files that need the macros.  That would
be easy to do; the only real cost is that of having another
include file to worry about.

These days, it's routine for compilers to inline.  For
old fashioned compilers that don't inline, it's routine to optimize
away static functions that are never used.  So, from an optimization
viewpoint, this problem is relatively unimportant.
