Yeah, in clang at least the main enumeration has a type that is signed or unsigned, but each enumerator also has a type.
Actually scratch my suggestion, because SBTypeEnumMember already has GetType():
SBType
SBTypeEnumMember::GetType()
Which we can then figure out if it is signed or not.
So your patch looks good as is.
