string length is greater than the minimum ANSI C is required
to support.

From-SVN: r34997
* gcc.c (C specs [!USE_CPPLIB]): Invoke tradcpp if any of
-traditional, -ftraditional, or -traditional-cpp was given.
Do not pass -traditional to the preprocessor.
(.S spec): Likewise. Don't bother defining __ASSEMBLER__, the
preprocessor does it automatically.
* objc/lang-specs.h: Likewise. Don't bother defining __OBJC__.
* ch/lang-specs.h: Always use tradcpp. Do not pass
-traditional, -trigraphs, or -pedantic to the preprocessor.
* f/lang-specs.h (.F spec): Likewise. Don't bother defining
_LANGUAGE_FORTRAN.
From-SVN: r34995
* cppexp.c (LOGICAL): Delete macro.
(_cpp_parse_expr): Do not use UNARY for unary +. Implement ||
and && directly.
* cpphash.c (HASHSIZE): Increase to 4096.
(struct hashdummy): Add hash field.
(eq_HASHNODE): Compare unreduced hashes, then lengths, then
the string values using memcmp.
(cpp_lookup): Set dummy.hash.

* cpphash.c: (struct macro_info, alloc_macro, free_macro,
struct toklist_dummy): New.
(cpp_free_definition): Free macros with free_macro.
(count_params): Don't save paramter spellings. Save macro
information in a struct macro_info.
(parse_define): Don't allocate a token list.
(save_expansion): Allocate the macro's token list, and
save parameter spellings if necessary. Use TOKEN_SPELL.
(cpp_create_definition): Make list const.

Hoist test for excessive nesting to caller.
(push_arg_context): Returns void; takes just reader and token.
Do not call stringify_arg or get_raw_token.
(get_raw_token): Convert tail recursion through push_arg_context
to a loop at this level. Call stringify_arg here if appropriate.
(maybe_paste_with_next): Convert tail recursion to a while loop.
Hoist test of paste_level to caller.
(stringify_arg): Push arg context at beginning.
(cpp_get_token): Split out core into _cpp_get_token. Call
process_directive here. Throw away CPP_PLACEMARKER tokens.

do_pragma_implementation, do_pragma_poison, do_pragma_dependency,
parse_ifdef, validate_else): Use it.
(cpp_push_buffer): Tweak error message; abort if anyone tries
to push a buffer while macro expansions are stacked.

and/or xrealloc to PTR.
