I also would like to be able to do this but cannot as yet.

According to the gdb documentation, gdb can only correctly handle C++
correctly if the object modules are compiled in stabs (or maybe stabs+)
format.  Unfortunately djgpp doesn't support stabs format.

(i) Will V2 support more object formats ?

(ii) If not, how difficult would it be to add stabs format, is it just a
	matter of uncommenting some lines in the source, or is it hours
	of head-scratching frustration ?

(iii) (This just occured to me.)  Objcopy can change formats, presumeably,
	even if it would do the conversion, the required debugging information
	would still be missing in the new file.

Anybody know ?
