2239 * cppmacro.c (funlike_invocation_p): Re-disable macros enabled

2300 use the "__need_" hackery. It breaks them.
2301 * fixinc/fixincl.c(process - SEPARATE_FIX_PROC):
2302 Sometimes on DOS and BeOS the temp output file cannot be opened.
2303 Skip the file noisily. Ought to be fixed instead.

2367 (*tablejump_rjmp, *tablejump_lib, *tablejump_enh, *tablejump):
2368 Make operand 0 input only, clobber it. Use UNSPEC, not a bogus
2369 MEM for program memory word reference. Do not add the label to
2370 the table index in each of the asm output templates, instead ...
2371 (casesi): ... do it in RTL. Adjust to match the above change.
2373 2000-12-02 Bernd Schmidt <bernds@redhat.co.uk>

2409 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
2410 invisible reference in registers, but then spilled to the stack.
2411 Remove code to emit a second stab for such parameters; it attempts
2412 to describe the value's location by introducing a synthetic C++
2413 `reference' type, and then saying the stack slot has that
2414 reference type. This loses type information (breaking GDB's
2415 `ptype' command, among other things) just to describe a location
2416 which stabs can represent correctly in other ways.
