I believe that 4.3 and 4.4 had a bug.  Gfortran 4.5 is doing the right
thing.  The deleted feature is 

  (2) Branching to an END IF statement from outside its block.
      In Fortran 77, and for consistency also in Fortran 90, it was
      possible to branch to an END IF statement from outside the IF
      construct; this has been deleted.  A similar result can be
      achieved by branching to a CONTINUE statement that is immediately
      after the END IF statement.

Your GOTO 50 is inside the its block.  I also believe that there was
a long thread in fortran@gcc about this (non)feature.  I'll see if 
I can find it.
