cpplib.c (initialize_char_syntax): Use ISALPHA and ISALNUM so it'll work on non-ASCII platforms.

	* cpplib.c (initialize_char_syntax): Use ISALPHA and ISALNUM
          so it'll work on non-ASCII platforms.  Always consider $ an
          identifier character.  Take no arguments.
	  (cpp_reader_init): Call initialize_char_syntax with no
          arguments.
	  (cpp_start_read): Don't call initialize_char_syntax again.
          Clear is_idchar['$'] and is_idstart['$'] if not
          opts->dollars_in_ident.
	* cpplib.h (struct cpp_reader): Replace void *data element by
          cpp_options *opts.  Rearrange elements to make gdb printout
          less annoying (put buffer stack at end).
	  (CPP_OPTIONS): Get rid of now-unnecessary cast.
	* cppmain.c: s/data/opts/ when initializing cpp_reader
          structure.
	* c-decl.c: Likewise.
	* objc/objc-act.c: Likewise.
	* fix-header.c: Likewise.
