`__bb_init_func' once per object module, passing it as its sole
argument the address of a block allocated in the object module.

can take a short cut in the definition of this macro and use the

The first word of this block is a flag which will be nonzero if the
object module has already been initialized. So test this word
first, and do not call `__bb_init_func' if the flag is nonzero. */
