	* cp-lang.c (c_reset_state): New dummy routine.
	* cp-tree.h (finish_file): Move prototype to c-common.h.

From-SVN: r69224

	* cpplib.h (CPP_AT_NAME, CPP_OBJC_STRING): New token types.
	(struct cpp_options): Add narrow_charset, wide_charset,
	bytes_big_endian fields.  Remove EBCDIC field.
	(cpp_init_iconv, cpp_interpret_string): New external interfaces.

	* cpphash.h: Include <iconv.h> if we have it, otherwise
	provide a dummy definition of iconv_t.
	(struct cpp_reader): Add narrow_cset_desc and wide_cset_desc fields.
	(_cpp_valid_ucn): Update prototype.
	(_cpp_destroy_iconv): New prototype.

	* doc/cpp.texi: Document character set handling.
	* doc/cppopts.texi: Document -fexec-charset= and -fexec-wide-charset=.
	* doc/extend.texi: Delete entire section on multiline strings.
	Rewrite section on __FUNCTION__ etc now that these are
	variables in C.

	* cppucnid.tab, cppucnid.pl: New files.
	* cppucnid.h: New generated file.
	* cppcharset.c: Include cppucnid.h.  Lots of commentary added.

	character names are only valid in C++ and C99" to a warning.
	Issue the "meaning of \[uU] is different in traditional C"
	warning here.  Take care not to let iconv see an invalid UCS
	value if we get a malformed UCN.  Issue an error if we don't
	have iconv.
	(cpp_interpret_charconst): Moved here from cpplex.c.  Use
	cpp_interpret_string to do the heavy lifting.

	* cppinit.c (cpp_create_reader): Initialize bytes_big_endian,

	Most of the work handed off to cpp_interpret_string.
	Call fix_string_type here.
	* c-parse.in (STRING_FUNC_NAME, VAR_FUNC_NAME): Replace with
	FUNC_NAME, throughout.
	(OBJC_STRING): New token type.

	* objc/objc-act.c (build_objc_string_object): No need to
	handle string constant concatenation.

cp:
	* parser.c (cp_lexer_read_token): No need to handle string
	constant concatenation.

testsuite:
	* gcc.c-torture/execute/wchar_t-1.x: New file; XFAIL wchar_t-1.c
	everywhere.
	* gcc.dg/concat.c: Concatenation of string constants with
	__FUNCTION__ / __PRETTY_FUNCTION__ is now a hard error.
	* gcc.dg/wtr-strcat-1.c: Loosen dg-warning regexp.
	* gcc.dg/cpp/escape-2.c: Use wide character constants where
	necessary to avoid multi-character character constant warning.
	* gcc.dg/cpp/escape.c: Likewise.
	* gcc.dg/cpp/ucs.c: Likewise.

	* cppfiles.c, cpphash.c, cppinit.c, cpplex.c, cpplib.c
	* cppmacro.c, cpppch.c, cpptrad.c, cppspec.c: Convert to
	ISO C: new-style function declarations, no need for PARAMS,
	no special punctuation on indirect function calls, use string
	constant concatenation where convenient.
