Change 91008 by rwatson at rwatson_freefall on 2006/02/04 00:11:29

	Before casting to an integer, first cast a pointer to (uintptr_t).
	That way the truncating cast occurs on a compatible type.
	
	We need to investigate if Solaris has 64-bit versions of the records
	that place pointers in tokens, and/or if they just use a 64-bit arg
	token instead here.  That way we could avoid truncating the
	addresses.
