           Summary: g77 compiles illegal code in testsuite
           Product: gcc
           Version: 3.4
            Status: NEW
          Severity: normal
          Priority: P2
         Component: fortran
        AssignedTo: billingd@gcc.gnu.org
        ReportedBy: billingd@gcc.gnu.org
                CC: gcc-bugs@gcc.gnu.org

Steve Kargl reported a problem with 20000601-2.f.  The test is one of mine. I 
will check over my notes and come up with a fix.

I'm running the Fortran 77 code in gcc-testsuite-3.3.tar.bz2
through g95 and I've found that 20000601-2.f contains
illegal code for Fortran 95 and probably Fortran 77.  I don't
have the Fortran 77 standard handy, but I believe the code is
illegal; yet g77 compiles the code without warning or error.
