As we decided at the last meeting, the only proposals which we plan 
to consider are ones which either correct errors in the changes we 
have made to Dwarf 2 which would make implementing support for Ada 
more difficult, or proposals which remove impediments to implementing 
support for Ada.

I see no difficulty with implementing this as a vendor extension,
should you wish to do so.

Since this does not require any change to Dwarf to enable you to
implement such a vendor extension, and there is nothing in the 
existing standard which would impede your doing this, it would 
appear that such a proposal would not fall into either of the
categories we approved.

I believe that the committee anticipates that much of Ada support
would be in the form of vendor extensions, for the many reasons
which we gave at the committee meeting.   



I'd welcome a list of the areas where Dwarf can enable Ada
support, keeping within the guidelines that we previously adopted.
