Re: Wrong warning? ISO C restricts enumerator values to range of ‘int’

Maybe I don't understand what you are asking but from reading the code
and relevant testcases, it seems that:

* Unsigned integer constants for enum values are handled just fine by
GCC as a extension to the C language. (See testsuite/gcc.dg/enum1.c).
* Being an extension, it is warned by -pedantic.

So everything is working as expected, isn't it?

Cheers,

Manuel.
