Both gdb 3.3 and 3.4 fail when debugging a Fortran program under SunOS 4.x
when the Fortran program uses an "external" statment.  The following patch
will apparently fix the problem without breaking anything else as far as
I know.  I'm not sure if this is technically the best fix... but it works!

      }
    return sym;
  }
