Well, after a bit of research, I realised that it is a bad idea to take 
advantage of some of the nice features of GLD and BFD.

If you use GLD (1.94 or 2.0) to translate from a.out into COFF file formats 
then you lose nearly all of the symbolic debugging info. Only addresses 
are preserved and GDB is lost without more information.

So, it is currently impossible to produce COFF-68k executables with debug info
in them since gas-1.92.3 does not correctly produce COFF output (at least it didn't
last time I tried it - maybe I should try it with a newer version of BFD lib) 
for 68k.

It would be good if someone could look into the following:

1.  To be able to transliterate a.out debugging info into COFF debugging info
	using BFD (or some other backdoor method inside GLD).

2. To fix GAS to produce 68k COFF output properly. 

I don't know of any 68k ICE/Emulators which accept a.out format, with the
possible exception of VxWorks tools and COFF is very useful to have around.
