[Bug fortran/29813] -std=F95/F2003: Warn or error when using a non-declared variable with implicit none

[tobi at gcc dot gnu dot org]

------- Comment #4 from tobi at gcc dot gnu dot org  2007-10-05 22:33 -------
Ok, last comment for tonight: the second option would fail for the perfectly
legal
 subroutine a(arr)
    implicit none
    dimension arr(5)
    real arr
 end
