   	additional question: are sizeof(long) different on sparc32 and sparc64?
   	if so, routing socket alignment (ROUNDUP in sys/net/rtsock.c will
   	have the similar problem.


sizeof(long) is different between 32bit SPARC and 64bit SPARC.  note that
ultrasparc hardware is capable of running both and (we eventually hope that
a :-) NetBSD/sparc64 64bit kernel can/will run both.  the same problem will
apply to 64bit mips ports that want to run 32bit applications.
