That must have been a really really old and buggy version of gfortran:
as already explained, the exit statement in Fortran 90/95 is the
equivalent of C's break in a loop (and cycle is the equivalent of
C's continue in a loop). I can hardly imagine that any official version
of gfortran would not have gotten that rather basic feature right.
