>Description:
	Fix provided for certain regex(3) features involving
	expression engine opcodes>=16 that fail in the 64-bit
	environment.
>How-To-Repeat:
	run vi or ex on NetBSD-Alpha, type /\<o\> above some lines like:

		how now brown cow
		how now o brown cow
		here is another o line

	You won't match any o at all.  Probably is in grep and others too.

>Fix:
	Apply enclosed patch. Note, you could also just get rid of
	all the longs, there aren't too many...this fix at least
	makes the (incorrect) longs work, with a much smaller patch.
	All it does is add L's to the constants that get shifted into
	bit 31.  It would probably also work to define them with an
	(unsigned) cast included.

	Apply patch in /usr/src/lib/libc/regex
