You could take the exact same C program and run it on a compiler+computer with sizeof(void *) == 64 or 128 or 1000000, and it should handle a correspondingly huge problem.

I am not sure that would be valid. You could also use a defined constant as the limit in the Fortran program. In other words, you could argue that SIZE_MAX is part of the program, the same as the Fortran array size is defined in the program. But I am not sure it would be invalid either... just wondering.

Wouldn't it be possible to, with a really strange number format for integers, define SIZE_MAX as INFINITY? C doesn't require twos-compliment numbers, after all.

That's a very interesting question that got me thinking for quite a while and the only conclusion I reached is that you deserve an upvote.
