5168 dummy-conditions.o. Eliminate references to insn-conditions.o,
5169 or change them to build/gencondmd.o, as appropriate. Remove

5195 (print_path): Avoid unnecessary use of printf.
5196 (print_header): New function, split out of main. Distinguish
5197 more carefully between an unrecognizable insn and an insn that
