Options

c-lex.c (c_lex): Remove CPP_INT, CPP_FLOAT cases. 

	* c-lex.c (c_lex): Remove CPP_INT, CPP_FLOAT cases.
	* c-parse.in (yyerror, _yylex): Similarly.
	* cppexp.c (parse_number, parse_defined, lex, _cpp_parse_expr):
	Don't use CPP_INT, CPP_FLOAT; CPP_NUMBER is enough.
	Update comments.
	* cpplib.h (CPP_INT, CPP_FLOAT): Remove.
	* cp/spew.c (read_token, yyerror): Remove CPP_INT, CPP_FLOAT cases.
