539 $outputs. Do not run configure.lang from config.status.
540 Rearrange warning-flag logic to correspond to what the
541 makefile wants. Put special vax stage1 options in
542 @stage1_flags@ not @stage1_warn_cflags@. Don't do anything

558 generation rules. Wrap all rules that change the current
559 directory in parentheses; pmake doesn't spawn a new shell for
560 each command. Expunge all references to $(P). When one
561 command depends on another and they're run all at once, use &&
