Hi Andy,

Thanks for your quick response, since I was (am) getting a little desperate.

Correct.

How and when? Is somebody working on an improved DJGPP to include this option?

It reports: GNU assembler version 2.6 (m68k-coff).Looks to me like it really
is a 68k assembler.

> 2) 'ld --version'

It only reports: ld version 2.6 (with BFD 2.6)But when I use 'ld -help' I get:

c:/djgpp/bin/ld.exe: supported targets: coff-i386 pe-i386 pei-i386 coff-m68k
versados srec symbolsrec tekhex binary
c:/djgpp/bin/ld.exe: supported emulations: i386go32 i386coff i386pe m68kcoff

So the m68k is mentioned here. But for some reason ld tries to procuce i386
code. I could not figure out if it is possible to force ld to produce m68k
code (none of the switches listed upon 'ld -help' to me seemed like it would
do the trick)

I only have an old djgpp.djl file which belonged to the original DJGPP
installation to compile for i386 target (it says 'OUTPUT_FORMAT("coff-go32")'
in line 1), but I don't think any of the new executables make use off this
file, since after I removed it I got the same error messages.

Any ideas?
