That will make the underlying C++ type unsigned int on systems
with 32-bit ints.
(Signed int may still be used on systems with 64-bit ints).

But in C, are all enums of type (signed) int?

Not sure that matters too much, given that the sizes will be the same.

I like the suggestion of using explicitly sized (signed or
unsigned) integers.  It avoids C/C++ differences.

Though, I would be interested to hear if there is a C++ compiler
that breaks C compatibility by using enum types smaller than int.
