This was already done, but does not solve the 0xFFFF source lines
limit because it is a COFF limit and not a limit of the debugging
information itself.

Reconfiguring the binutils and gdb is very easy...

I don't how difficutl this would be but it should be also
possible.
But all of this is not the main work. The main work should be investigated
in changing the DJGPP startup code to load and execute other
formats than COFF and I can't imagine that this is an easy task.

If you are using pgcc you have already support for stabs debugging
information, because it is applied there (I checked it).

Binutils is an other topic. To build the binutils right for
DJGPP you need the sources already patched for DJGPP.
The ported binutils 2.8.1 will be available in the next time.
I made already all needed patches and now waiting only until
they are accepted by the maintainer of the binutils.
