229 makefile wants. Put special vax stage1 options in
230 @stage1_flags@ not @stage1_warn_cflags@. Don't do anything

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

251 deleted on make clean. Force OUTPUT_OPTION='-o $@' in stage2

319 return types with -pedantic to when the function type is
