Makefile.in (cppexp.o): Depend on cpphash.h.
* Makefile.in (cppexp.o): Depend on cpphash.h.
* cppexp.c (cpp_lex): Handle `defined (xxx)' for poisoned xxx.
Include cpphash.h.
* cpphash.c (special_symbol): Handle plain `xxx' for poisoned xxx.
* cpplib.c (do_define): Generalise to handle poisoned definitions,
redefining poisoned identifiers, etc.
(do_undef): Don't allow poisoned identifiers to be undefined.
(do_pragma): Add #pragma poison.
(do_xifdef): Handle `#ifdef xxx' for poisoned xxx.
* cccp.c: Add T_POISON node type.
(special_symbol): Handle `defined(xxx)' and plain `xxx' for
poisoned xxx.
(do_define): Generalise to handle poisoned definitions,
redefining poisoned identifiers, etc.
(do_undef): Don't allow poisoned identifiers to be undefined.
(do_pragma): Add #pragma poison.
(do_xifdef): Handle `#ifdef xxx' for poisoned xxx.
* c-pragma.c (handle_pragma_token): Ignore #pragma poison.
* c-pragma.h: Add ps_poison state. We now always have generic
pragmas.
