 391  * There are two versions of most of the return macros. The default version is
 392  * safer, since it avoids side-effects by guaranteeing that the argument will
 393  * not be evaluated twice.
 394  *
 395  * A less-safe version of the macros is provided for optional use if the
 396  * compiler uses excessive CPU stack (for example, this may happen in the
 397  * debug case if code optimzation is disabled.)
