Why not GNU all the way?! Then you'll have all the GNU power ;-)
Ie. use GNU CC and binutils configured for m68k-coff... That's what we do.
And we used MRI before. There's even a switch for GNU 'as' that makes it
understand MRI syntax!
There is a CrossGCC Faq somewhere on the web on how to build cross-platform
tools.
Look at sourceware.cygnus.com...

Subject: Using GDB with MRI cross compiler ?
Hello,
On Sparc-SUN-Solaris2.6 :
I want to use gdb on m68 target with GDB 4.18.
Lot of soft already exist on this target. These softs were built with
the MRI tools (microtech: mcc68k v4.4, asm68k v7.0, lnk68k v7.0)
throught platine utilities
(v4.30).
A) First I try to convert ieee executable file ( output of MRI linker
with symbol table and debug informations .xray) into a elf file with
objcopy (GNU binary utilities
2.9.1). In gdb, most of symbol were lost and none is a debbuging
symbol. So, I try to convert ieee output file of MRI tools into Coff or
Aout format with objcopy
but GDB doen't recognized these output !
So i suppose that the debbuging symbole are the results of GCC and
objcopy should not convert all the symbol available in ieee into elf.
Something is wrong or not
?

B) I try to link with GNU LD the relogeable file issued from MRI
compiler /assembler.
First the numerical named section isn't accepted in MRI script file
using objcopy. Change the name into alphanumerical works well.
But the ieee input format seems to be unrecognized.

I have a bad configuration or option or you know a tool which permits
use MRI tools with gdb ?
Your help would be greatly appreciated.
