Really? As it happens I do only have a partial source tree, I saved
some copying effort by not bothering to take sys/arch/* for any but i386
(at the minute). But I guess this isn't the definition of complete...
But assuming that is the case, rather than collapsing with an obscure

Does it really matter? The toolchain change isn't altering the ABI is it?

I think that's an error. I have had complete source trees on most of
my systems forever, and until I did a build using the new toolchain just
for fun a couple of weeks ago (on a different system than the one being
considered here), I'd never done a build of a large portion of the tree.
The source is there for doc, and in case something breaks that I can
quickly fix. It isn't there so I can rebuild it for no rational gain...
I suspect that's true of most of the end users.
ps: with your fix installed, all the pkgsrc build problems went away
with no mention of USETOOLS in mk.conf - thanks for that.
