well:

	sizeof (CORE_ADDR) >= TARGET_PTR_BIT / HOST_CHAR_BIT

	sizeof (LONGEST) >= TARGET_LONG_LONG_BIT / HOST_CHAR_BIT

	CORE_ADDR is a host integer type large enough to hold
		a canonical target address

	LONGEST is the largest host integer type supported by the host

giving:

	sizeof (LONGEST) >= sizeof (CORE_ADDR) :-)

Much code (unfortunatly?) assumes that a CORE_ADDR can be passed into a
LONGEST (whether doing so is correct or not).
