[Bug fortran/18778] New: ENDFILE is not functionnal

[coudert at clipper dot ens dot fr]

This bug seems not to have been reported yet. It is the cause of failure for the
NIST FM411 fortran test. The reduced test case is:
--------------------------------------------
      program test
      implicit none
      integer i

      endfile(8)
      rewind(8)
      read(8,end=0023) i
      print *, i
      stop
      
 0023 print *, 'End of file'
      stop
      end
--------------------------------------------

The correct behaviour is:
$ g77 test.f; ./a.out
 End of file

while gfortran currently doesn't handle it:
$ gfortran test.f; ./a.out
At line 7 of file test.f
Fortran runtime error: Corrupt unformatted sequential file

[This was tested on i686/linux with gcc version 4.0.0 20041202]

it is really not endfile, it is endfile not creating a file if it is called on a
unit that does not yet exist.


confirmed.
