The C++ 1.2.1 translator finds no errors in the following fragment, but
it omits the typedef in the C source output and the C compiler chokes:

------------------------------------------------------------------------
struct x {
	typedef char *charptr;
	charptr cp;
};
------------------------------------------------------------------------

This is of course illegal syntax for both C++ and C, but our C compiler
flags this error and C++ 1.2.1 does not.

Is there any stylistic or operational reason why typedefs shouldn't
be permitted in member lists?  It seems like an omission to me since
it's possible to declare typedef-names in other ways in member lists.
Section r.8.7 of the C++ book specifically rules out typedefs in member
lists.
