533 identifier character. Take no arguments.
534 (cpp_reader_init): Call initialize_char_syntax with no
536 (cpp_start_read): Don't call initialize_char_syntax again.
537 Clear is_idchar['$'] and is_idstart['$'] if not
538 opts->dollars_in_ident.
540 * cpplib.h (struct cpp_reader): Replace void *data element by

581 * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c
582 to handle wide character constants in #if directives. The
583 function now returns a HOST_WIDE_INT, and takes a third

585 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
586 MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of

1392 The strategy we now use is to pre allocate the top_elt along
1393 with the EH context so that each thread has its own top_elt.
