ISO C allows compilers to make enums smaller than int if their enumerated values would all fit in the range of a smaller type. In practice, I suspect that in relevant compilers, all enums whose values fit in the range INT32_MIN to INT32_MAX (inclusive) are the same size as int. ISO C allows compiler to break that assumption, but those that do would break code that works fine in other compilers, making the compiler look bad, for no significant benefit. I conjecture that such compilers are not popular. Let's statically assert that my assumption holds. If all goes well, GLib will continue to compile on every relevant platform; if it fails to compile on some platform as a result of this change, then there are probably a lot of naive uses of enums that need auditing for this assumption.
