/* We link this module statically for convenience. If compiled as a shared

defined in other libraries to be used in static initializers here. The

DEFERRED_ADDRESS macro is used to tag the slots where such addresses

appear; the module init function must fill in the tagged slots at runtime.

The argument is for documentation -- the macro ignores it.
