Once you get into pragmas you start forcing one specific compiler to
be used.

Also I happen to think that gcc is right.  The expression is useless
and hardly qualifies as defensive.

If a type can not have a value outside a certain range, then there is
nothing defensive about checking that it is in the only range it can
be in.
