>Description:
	Compiling BIND (as part of regular NetBSD source tree)on
	an alpha, with -mcpu=ev6 causes gcc to detect an internal
	error and abort, while compiling the host utility

>How-To-Repeat:
	Add 
		COPTS+=-mcpu=ev6
	to /etc/mk.conf on alpha (probably needs to be an ev6 alpha to be safe),
	and do a regular NetBSD-current build (build.sh ...)

	Expect to see...

	Easy workaround is just to not use -mcpu=ev6 ...
