Hi David,

Some time ago I also looked into this and realised that it may even be
possible to do something like this:
static __inline void
EV_SET(...)
{
}
/* Compatibility for code that tests #ifdef EV_SET. */
#define EV_SET EV_SET
This has the advantage that you get pretty neat error messages in case
you get the typing of arguments wrong, as if you're just calling a
function incorrectly. The EV_SET() macro is never used in contexts
that require constant values.
