           Summary: 2d level configure script does not recognize gcc/gcc/cp
                    as build dir.
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: critical
          Priority: P2
         Component: bootstrap
        AssignedTo: gnat-dev at buzco dot nyct dot net
        ReportedBy: gnat-dev at buzco dot nyct dot net
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i586-pc-linux-gnu
  GCC host triplet: i586-pc-linux-gnu
GCC target triplet: i586-pc-linux-gnu

When doing configure w/o using --languages=, and the ada and cp dirs
   both present, it picks up the ada subdir but not the cp subdir.

   Further investigation shows that it is the presence of "Makefile.in" but
   not "Make.lang.in" that causes the dir to be started in the build tree.
   The ada subdir has both, the cp subdir has only "Make.lang.in".

   This did not occur in main trunk last I looked, but I have not
   investigated what the diff is there, yet.
