Hmmm, I don't remember having submitted the patch to emit these subrange
types. Maybe somebody else managed to add this capability already?
Do you confirm these types are emitted for modular types (for instance
"type Mod_Type is mod 4")?

Also, FYI, we made a very similar change in GDB to support these types.
We did factor out a bit the code that extracts constant bound values
into a function. And we also sprinkled a bit more of the handlers for
DW_TAG_subrange_type cases. I am attaching the patch (against GDB 6.0,
but shouldn't be too hard to adapt).
