This still looks like a GCC issue.  The C standard includes values stored in other const variables as permitted in integer constant expressions.

5.4 is almost a year old, so maybe this was fixed. However, I'm not sure it would be so bad to have a workaround for this compiler?

There is already a warning that clang should be used (which I, of course, switched to; I prefer it anyway). But having a workaround to make it work with GCC, even in a basic, unsupported way, is probably still good?
