Might be off topic, but where does c99 state range of long long
larger than range of int? My reading of the c99 standard states the
same thing as c89 and hence c++98 [and probably later revisions]
regarding sizeof various signed integral types. That is sizeof(X) ==
1 for any integral type X, is legal.
So that if the machine is a 'natural' 32 bit word machine, then
CHAR_BIT == 32 is legal.
