Cool.  I'll have to try that. :-)

I've been using this for years with great results.  I know that
Charles used to build stuff at -O6, so I had a good feeling that
things were at least tested by a competant person.  I don't know if he
still does that, but I still use this for the system, libraries and
binaries (as opposed to non-NetBSD stuff):

	-O6 -m486 -pipe -fno-strength-reduce

For stuff that doesn't come with NetBSD, I'm a little more nervous
using -O6 (since I've seen stuff in code that gets optimized away,
breaking things, though not often).  So, I use this for other stuff:

	-O2 -m486 -pipe -fno-strength-reduce
