1239 * cppmacro.c (funlike_invocation_p): Re-disable macros enabled

1368 Make operand 0 input only, clobber it. Use UNSPEC, not a bogus
1369 MEM for program memory word reference. Do not add the label to
1370 the table index in each of the asm output templates, instead ...
1371 (casesi): ... do it in RTL. Adjust to match the above change.
1373 2000-12-02 Bernd Schmidt <bernds@redhat.co.uk>

1409 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
1410 invisible reference in registers, but then spilled to the stack.
1411 Remove code to emit a second stab for such parameters; it attempts
1412 to describe the value's location by introducing a synthetic C++
1413 `reference' type, and then saying the stack slot has that
1414 reference type. This loses type information (breaking GDB's
1415 `ptype' command, among other things) just to describe a location
1416 which stabs can represent correctly in other ways.

4773 $outputs. Do not run configure.lang from config.status.
4774 Rearrange warning-flag logic to correspond to what the
4775 makefile wants. Put special vax stage1 options in
4776 @stage1_flags@ not @stage1_warn_cflags@. Don't do anything
4777 with extra_c_objs, extra_cxx_objs, or extra_cpp_objs.

4785 warning options via a three level scheme so that -pedantic and
4786 -Wtraditional are not used for non-C front ends: LOOSE_WARN,
4787 STRICT1_WARN, STRICT2_WARN -> $(@D)-warn, GCC_WARN_CFLAGS ->

4791 LANG_FLAGS_TO_PASS. Add OUTPUT_OPTION to all object-file
4792 generation rules. Wrap all rules that change the current
4793 directory in parentheses; pmake doesn't spawn a new shell for
4794 each command. Expunge all references to $(P). When one
4795 command depends on another and they're run all at once, use &&
4796 to separate them, not ;. Add libgcc_s$(SHLIB_EXT) to files
4797 deleted on make clean. Force OUTPUT_OPTION='-o $@' in stage2
4800 * objc/Make-lang.in: Wrap all rules that change the current
4801 directory in parentheses. Expunge all references to $(P).
