* c-decl.c (start_decl): Unconditionally issue error for
'typedef foo = bar'.
(finish_decl): Remove special case for TYPE_DECL with initializer.
* doc/extend.texi: Delete "Naming Types" section. Change all
cross-references to that section to refer to "Typeof" instead.
Add the useful safe-max()-macro example from "Naming Types" to
"Typeof", rewritten using that extension.
gcc/cp:

'typedef foo = bar'.

Also make duplicate modifiers such as "short short" into hard
errors.

* builtins.def [DEF_GCC_BUILTIN]: Require an explicit ATTRS
argument. Mark BUILT_IN_RETURN, BUILT_IN_EH_RETURN,
BUILT_IN_LONGJMP and BUILT_IN_TRAP as noreturn, the ISO C99
floating point unordered comparisons (e.g. __builtin_isgreater)
as const, and leave the remaining GCC_BUILTINs unchanged.
