Yes.  There was a bug with expr(1) on big-endian machines.  The fix was 
checked in, and will be there in 1.0.

cuserid() is in -lcompat (But it shouldn't ever be used since it means 
different things on different systems, see the manpage).  I did the 
i386 sigsetjmp & siglongjmp() --- a m68k user needs to do the same.
