Dunno about the ^Ms, but I'm guessing that the -B option needs to
be used to properly use -v on an uninstalled g77.  (Maybe for
gcc too, if the specs file is suitably important/different?)

So, if the test stuff is modified to do `<tree>/<command> -B<tree>/ -v',
or similar, it should resume working.  (No relevance to b-trees here.  :)
