        One major adavantage of macro conversion is that GCC doesn't do
cross-procedural optimization, nor cross-source-file inlining of small
functions.  Making "one-line" simple functions macros instead removes both
of these restrictions.

        Other compilers may have smarter optimizers, but this is still
likely to be worthwhile.
