AFAIK, that was never the case with the DEC/Compaq/HP C compilers for OpenVMS.

The sizes of "int" and "long" were and are 32 bits, and "long long" was 
later added and was and is 64 bits.

OpenVMS Alpha prior to V7.0 used 32 bits sign-extended for virtual 
addresses, and with V7.0 and later and with 64-bit compilers use 32- or 
64-bit variables for addresses depending on how the application is 
written and built.  That change certainly broke code that assumed the 
size of a pointer, but the folks writing the application code had to 
ask for 64-bit pointers to get into that trouble.
