This is not actually a Fortran issue as such, it's all about a specific
compiler (GNU Fortran).

If we overlook the nonstandard type in the declaration, and agree
that the compiler will accept 'integer*8', then the program is
still invalid Fortran.  It's technically not a Fortran issue.  It
is a programmer issue.
