 there was another build failure since my change, and then i saw the
 failure myself just now.  i think the problem is that insn-opinit.h
 is included by files many many files.  the previous fix i'm fairly
 sure is a valid and good change, but it didn't fix the problem here,
 which should be fixable by this:
 
 +DPSRCS+= insn-opinit.h
 
 in backend/Makefile.
 
 i'll commit this when my build works (i don't expect to reproduce it
 again easily.)
