Hi everyone.

As far as I have understood, the following configurations are the most
common "C" implementations for word length:

(16 bit architecture)
char   =  8 bits
short  = 16 bits
int    = 16 bits
long   = 32 bits

(32 bit architecture)
char   =  8 bits
short  = 16 bits
int    = 32 bits
long   = 32 bits

Does anyone know if this configuration is supported (presumably on 32-bit
machines):
char   =  8 bits
short  = 16 bits
int    = 32 bits
long   = 64 bits

All machines I have tried C on have conformed to one of the former
configurations, none to the latter.
