It occurs to me that I may not have made this clear enough.
A portable, standard-conforming program does not become nonportable
or non-conforming upon addition of "volatile" qualifiers (assuming
of course the addition is done according to the type rules).
It is only the actual reliance upon the property of volatility that
would be nonportable. (e.g. device register)
int main() { volatile int i; return i = 0; }
is a portable, standard-conforming program.
