I've fixed this by changing the code in mtype.c, line 5984:

Type *TypeEnum::toBasetype()
{
    if (sym->scope)
    {
-    sym->semantic(NULL);    // attempt to resolve forward reference
+    sym->trySemantic(NULL);    // attempt to resolve forward reference
    }

and adding this code to enum.c:

void EnumDeclaration::trySemantic(Scope *sc)
{
    unsigned errors = global.errors;
    global.gag++;
    DsymbolTable *savetable = symtab;
    semantic(sc);
    global.gag--;
    if (errors != global.errors)
    {   
    global.errors = errors;
    symtab = savetable;
    }
}
