2676 block that consists only of notes and labels.

2681 * cppmacro.c (funlike_invocation_p): Re-disable macros enabled

2742 use the "__need_" hackery. It breaks them.
2743 * fixinc/fixincl.c(process - SEPARATE_FIX_PROC):
2744 Sometimes on DOS and BeOS the temp output file cannot be opened.
2745 Skip the file noisily. Ought to be fixed instead.

2809 (*tablejump_rjmp, *tablejump_lib, *tablejump_enh, *tablejump):
2810 Make operand 0 input only, clobber it. Use UNSPEC, not a bogus
2811 MEM for program memory word reference. Do not add the label to
2812 the table index in each of the asm output templates, instead ...
2813 (casesi): ... do it in RTL. Adjust to match the above change.
2815 2000-12-02 Bernd Schmidt <bernds@redhat.co.uk>

2851 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
2852 invisible reference in registers, but then spilled to the stack.
2853 Remove code to emit a second stab for such parameters; it attempts
2854 to describe the value's location by introducing a synthetic C++
2855 `reference' type, and then saying the stack slot has that
2856 reference type. This loses type information (breaking GDB's
2857 `ptype' command, among other things) just to describe a location
2858 which stabs can represent correctly in other ways.

2901 (expand_tree_builtin): Handle BUILT_IN_IMAXABS.
2902 * extend.texi: Document builtin imaxabs.
2904 2000-12-01 Joseph S. Myers <jsm28@cam.ac.uk>
2906 * c-common.c: Include "defaults.h".
