If I remember right, a F77 compiler will not necessarily be able to
compile Fortran IV code (I don't have any information about Amiga
Fortrans specifically).  There are statements, like DEFINE FILE, which
are not included in the F77 standard.  Also, loop semantics have changed:
I beleive a F77 loop will always execute once; not so with Fortran 66
(i.e. Fortran IV) loops.

So you should make sure the compiler explicitly supports F66.

I don't have the Fortran standard in front of me, so I'm not 100% sure
of the above (only 99%).
