I talked with Riccardo on IRC, and the patch fixed that particular 
problem, so we are back at the d0 linking issue. In the meantime I 
spotted two warnings in the build log for m68k. One is that two floating 
registers are declared in sysdepCallMethod on non linux systems, but 
aren't used. So I've attached a patch to remove them. It would be nice 
if Riccardo could give it a try, to see if they fix the warnings.

I've also seen another, weirder warning in the build logs:

This seems to  come from extensively long switch statements in verify.c. 
I was told by gcc hackers that factoring out of some of the long code in 
case statments into their own functions might help. So that's on the 
m68k task list as well.

cheers,
