Please go read THE STANDARD.

Long is not defined to be exactly 32 bits.  Long is defined to be AT LEAST
32 bits.  "long long" is a SYNTAX ERROR, not a violation of a size constraint.
A type named __int64 would be a perfectly legal extension which requires no
diagnostic message.

Having sizeof(long) < sizeof(int) is NOT PERMISSIBLE.

Sheesh.
