friend34.C: New test...

* g++.old-deja/g++.pt/friend34.C: New test; name injection of
	friend template declared within template class conflicts with
	nested class of the same name
	* g++.old-deja/g++.other/badopt1.C: New test; post-increment
 	is ignored
	* g++.old-deja/g++.other/decl1.C: New test; incorrect parsing of
	object with direct initializer as function declaration
	* g++.old-deja/g++.other/decl2.C: New test; duplicate initializers
	* g++.old-deja/g++.other/null2.C: New test; conditional operator
 	involving const pointer and NULL produces incorrect result
	* g++.old-deja/g++.other/typename1.C: New test; template-dependent
 	type name without `typename' should be rejected with -pedantic
