1229 * cppmacro.c (funlike_invocation_p): Re-disable macros enabled

1292 Sometimes on DOS and BeOS the temp output file cannot be opened.
1293 Skip the file noisily. Ought to be fixed instead.

1358 Make operand 0 input only, clobber it. Use UNSPEC, not a bogus
1359 MEM for program memory word reference. Do not add the label to
1360 the table index in each of the asm output templates, instead ...
1361 (casesi): ... do it in RTL. Adjust to match the above change.

1399 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
1400 invisible reference in registers, but then spilled to the stack.
1401 Remove code to emit a second stab for such parameters; it attempts
1402 to describe the value's location by introducing a synthetic C++
1403 `reference' type, and then saying the stack slot has that
1404 reference type. This loses type information (breaking GDB's
1405 `ptype' command, among other things) just to describe a location
1406 which stabs can represent correctly in other ways.

1450 * extend.texi: Document builtin imaxabs.
1452 2000-12-01 Joseph S. Myers <jsm28@cam.ac.uk>
1454 * c-common.c: Include "defaults.h".
