I've found some lead:
in enum.c:
void EnumDeclaration::semantic0(Scope *sc)
{
/* This function is a hack to get around a significant problem.
* The members of anonymous enums, like:
* enum { A, B, C }
* don't get installed into the symbol table until after they are
* semantically analyzed, yet they're supposed to go into the enclosing
* scope's table. Hence, when forward referenced, they come out as
* 'undefined'. The real fix is to add them in at addSymbol() time.
* But to get code to compile, we'll just do this quick hack at the moment
* to compile it if it doesn't depend on anything else.
*/
if (isdone || !scope)
return;
if (!isAnonymous() || memtype)
return;
for (size_t i = 0; i < members->dim; i++)
{
EnumMember *em = (*members)[i]->isEnumMember();
if (em && (em->type || em->value))
return;
}
// Can do it
semantic(sc);
}
If I remove the for loop and let semantic do its work the OP code compiles. But
I don't know the extent of this hack that's in place now, whether it's still
necessary or not.

There are more issues with these enums inside of brackets. Right now I'm having
the weirdest errors where referencing these enums doesn't work from a class
defined below it:
enum
{
wxUSER_ATTENTION_INFO = 1,
wxUSER_ATTENTION_ERROR = 2,
}
If they're each defined separately:
enum wxUSER_ATTENTION_INFO = 1;
enum wxUSER_ATTENTION_ERROR = 2;
then it works. I don't have a minimal test-case for this now (working on it),
but there's obviously some issues with the implementation.
