520 $outputs. Do not run configure.lang from config.status.
521 Rearrange warning-flag logic to correspond to what the
522 makefile wants. Put special vax stage1 options in
523 @stage1_flags@ not @stage1_warn_cflags@. Don't do anything
524 with extra_c_objs, extra_cxx_objs, or extra_cpp_objs.

538 LANG_FLAGS_TO_PASS. Add OUTPUT_OPTION to all object-file
539 generation rules. Wrap all rules that change the current
540 directory in parentheses; pmake doesn't spawn a new shell for
541 each command. Expunge all references to $(P). When one
542 command depends on another and they're run all at once, use &&
