Thanks for the clarification, Danny.  However, it doesn't really 
alter the diagnosis: include/c++/cwchar gratuitously refers to 
swprintf and vswprintf, thus requiring their prototypes to be in 
scope, when they have been elided because they do not conform to the 
ANSI/ISO specification.  That is a bug, for which we need to 
identify an appropriate resolution.
