Thanks a lot for testing Kaffe so persistently on a great number of 
platforms!

That's probably a problem in gcc for openbsd-68k, then. In any case, I'd 
  recommend against adding material to m68k/openbsd2/jit.h. I'd prefer 
to see it reduced to nothing, like Kiyo did for m68k/netbsd1/jit.h a few 
years ago. See 
http://www.kaffe.org/cgi-bin/viewcvs.cgi/kaffe/config/m68k/netbsd1/Attic/jit.h 
for details. I've CC:ed Kiyo, maybe he can remeber the details of the 
transition to a common m68k jit.h file.

For example, the openbsd m68k port seems to use CALL_KAFFE_FUNCTION 
which is only used by the i386 dgux port, and nowhere else in the code. 
that seems like, uh, some abandoned interface.

Hmm, you could also try building without optimization, with CFLAGS=-O0, 
to a) make the build faster, and b) make it easier on the compiler :)
