The C front end correctly copies the min, max, and precision
from the base type.

The C90 language doesn't have the clauses that C++ does that
allows for the narrowed precision.  I think one can construe
that in C99, with extended integral types, but there's not so
much to be gained that it's worth being incompatible with C90.
