If that is correct, than the default isn't "full", but
the proposed "no-compile-directory" ? Or maybe your compiler didn't emit
the comp_dir attribute in the debug info. I don't really know what
is the current default, and I'm now confused too. :-)

I don't think normal or default are good names (with IMO default being
a really bad name), because that'll confuse things a lot if we ever
flip the default.
