The old way of doing this is with defines. But all new code should be 
static inline functions when feasible. This way we can get typechecking 
on the parameters even when the configuration is disabled.

Even if the rest of the file uses defines, the new code should be
static inlines. Eventually, even the old defines will be converted.
