Grumble...

ANSI C says the same thing, although of course it only discusses int and
long. But the spec has always been clear that the implied type of an
integer constant is whatever it takes to hold it; you do not need an
explicit "L" suffix to make a valid constant. AIX's compiler is broken.

I'll do something about it. Would you check to see whether a macro like
#define SIXTYFOUR(x) x##LL
works?
