909 $outputs. Do not run configure.lang from config.status.
910 Rearrange warning-flag logic to correspond to what the
911 makefile wants. Put special vax stage1 options in
912 @stage1_flags@ not @stage1_warn_cflags@. Don't do anything
913 with extra_c_objs, extra_cxx_objs, or extra_cpp_objs.

921 warning options via a three level scheme so that -pedantic and
922 -Wtraditional are not used for non-C front ends: LOOSE_WARN,
923 STRICT1_WARN, STRICT2_WARN -> $(@D)-warn, GCC_WARN_CFLAGS ->
924 WARN_CFLAGS. Distinguish STAGE1_CFLAGS from BOOT_CFLAGS.
925 Add -I$(@D) and -I$(srcdir)/$(@D) to INCLUDES.
926 Set OUTPUT_OPTION, ZLIB, ZLIBINC. Do not set P,
927 LANG_FLAGS_TO_PASS. Add OUTPUT_OPTION to all object-file
928 generation rules. Wrap all rules that change the current
929 directory in parentheses; pmake doesn't spawn a new shell for
930 each command. Expunge all references to $(P). When one
931 command depends on another and they're run all at once, use &&
932 to separate them, not ;. Add libgcc_s$(SHLIB_EXT) to files
933 deleted on make clean. Force OUTPUT_OPTION='-o $@' in stage2
936 * objc/Make-lang.in: Wrap all rules that change the current
937 directory in parentheses. Expunge all references to $(P).
938 When one command depends on another and they're run all at
