[CLN-list] More questions about compiler warnings

[Jan Rheinländer]

https://stackoverflow.com/questions/2732085/is-there-a-way-to-make-enum-type-to-be-unsigned

The MS documentation is not too clear about the underlying type of
enumerations

But in the end, it's just a compiler warning. "make check" compiles
successfully either way.
