(SIM_OBJS,SIM_EXTRA_CFLAGS,SIM_EXTRA_CLEAN): Define. * configure.in: Simplify using macros in ../common/aclocal.m4. Call AC_CHECK_HEADERS(unistd.h). * configure: Regenerated. * config.in: New file. * simops.c: #include "config.h". #include <unistd.h> if present.
gencode.c, interp.c, simops.c: Created. So we've got something to hack on.
