1183 * cppmacro.c (funlike_invocation_p): Re-disable macros enabled

1245 * fixinc/fixincl.c(process - SEPARATE_FIX_PROC):
1246 Sometimes on DOS and BeOS the temp output file cannot be opened.
1247 Skip the file noisily. Ought to be fixed instead.

1314 the table index in each of the asm output templates, instead ...

1353 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
1354 invisible reference in registers, but then spilled to the stack.
1355 Remove code to emit a second stab for such parameters; it attempts
1356 to describe the value's location by introducing a synthetic C++
1357 `reference' type, and then saying the stack slot has that
1358 reference type. This loses type information (breaking GDB's
1359 `ptype' command, among other things) just to describe a location
1360 which stabs can represent correctly in other ways.

1404 * extend.texi: Document builtin imaxabs.
1406 2000-12-01 Joseph S. Myers <jsm28@cam.ac.uk>
1408 * c-common.c: Include "defaults.h".
1409 (WINT_TYPE, INTMAX_TYPE, UINTMAX_TYPE): Define.
1410 (c_common_nodes_and_builtins): Create string_type_node,
1411 const_string_type_node, wint_type_node, intmax_type_node,

1419 unsigned_ptrdiff_type_node.
