It's not currently possible to build various crosses with the current 
trunk due to warning issues.  I suspect this is the first of many 
patches to address those issues.

I'm not familiar with the code in question, but based on Maxim's comment 
the gcc_unreachable ought to be safe.  It could possibly even replace 
the entire else clause here, but I choose to avoid that simply because 
it's riskier.

I've confirmed the various m68k-* targets from config-all.mk will build 
after this patch.

Installed on the trunk.
