* cpplex.c (parse_name): No longer inline (premature optimization).
(do_pop_context): Fold into pop_context.
(pop_context): Returns int.
(lex_next): Hoist test for end of directive into pop_context.
(push_macro_context): Returns int; takes just reader and token.
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.
(_cpp_get_token): Convert tail recursion through
push_macro_context to a loop at this level.
(_cpp_glue_header_name, is_macro_disabled, stringify_arg,
_cpp_get_raw_token): Use _cpp_get_token.
(_cpp_skip_rest_of_line): Drop the context stack directly; do
not call pop_context.
(_cpp_run_directive): Call lex_next directly.
* cpphash.h: Prototype _cpp_get_token.
* cppexp.c (lex): Use it.
* cpphash.c (parse_define): Use it.
* cpplib.c (get_define_node, do_undef, parse_include,
read_line_number, do_line, do_ident, do_pragma, do_pragma_gcc,
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.

* cpplex.c (free_macro_args, save_token): Cast arg of free
and/or xrealloc to PTR.
(_cpp_init_input_buffer): Clear all fields of the base context.

* gensupport.c (process_rtx): Make rtl checking stop
complaining about the define_insn while it is being
converted from a define_insn_and_split.
From-SVN: r34968
* cppinit.c: (cpp_reader_init): Allow digraphs by default.
(handle_option): Set digraphs according to standard.
Merge OPT_lang_c89 handler with OPT_std_c89.
* cpplex.c: (lex_line, can_paste): Honour digraphs in
accordance with the digraphs flag.
* cpplib.h: (struct cpp_options): New option digraphs.
From-SVN: r34956
* stl_function.h (bind1st, bind2nd): Rename __opr to __oper,
as __opr is used internally by egcs.
* stl_numeric.h (__power, power): Likewise.
* stl_algo.h (transform): Rename __opr to __oper, as __opr is used
internally by egcs.
