1839         * Makefile.in: Make objects depend on d10v_sim.h.
1840         ({,SIM_}CFLAGS): Include configure dependent switches.  Setting

1851         (gencode{,.o},d10v-opc.o): Split compilation into creating object
1852         and linking.  Instead of linking in libopcodes.a, just compile
1853         d10v-opc.o directly to handle canadian cross.
1854         (CSEARCH): Add opcodes directory.
1855
1856         * configure.in (--enable-sim-cflags): New switch to allow user to
