Yes, if both are linked, the gdbarch initialisation is attempted to be 
done twice and gdb crashes. I could add an #ifdef to optionally ignore 
some parts of i386-tdep, but IMHO it's better to introduce a new file as 
DanielJ proposed. See the patch. I've moved both new builtin types and 
their initialisation to i386-common-tdep.c and modified all 
config/i386/*.mt files to require it. This approach shouldn't harm 
MarkK's effort at all.
Any objections or can I commit it?
