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.
