* cpplib.c (special_symbol): Rewrite. Don't copy things
multiple times. Handle __STDC__ specially. T_CONST
indicates a constant /string/. Don't handle T_*_TYPE and
T_SPEC_DEFINED. Use cpp_buf_line_and_col instead of
adjust_position. Determine the file buffer only if needed.
(initialize_builtins): Handle __SIZE_TYPE__,
__PTRDIFF_TYPE__, __WCHAR_TYPE__, __USER_LABEL_PREFIX__, and
__REGISTER_PREFIX__ with T_CONST special hashtab entries.
Don't provide __OBJC__; the driver does that. Provide
__STDC_VERSION__, using T_CONST. Use T_STDC for
__STDC__. Give install the length of all symbols defined.
(eval_if_expression): Drop code to insert and remove the
"defined" special symbol.
* cpplib.h: Remove SELF_DIR_DUMMY (no longer used). Remove
T_*_TYPE and T_SPEC_DEFINED from enum node_type; add T_STDC.
* cpphash.c (install): Drop the `ivalue' parameter. Constify
the `value' parameter. All callers changed.
* cpphash.h (install): Change prototype to match.
(union hashval): Remove `ival' member.
* cppexp.c (cpp_lex): Handle `defined' here.
