The checking of printf format strings needs a few more builtin types.
For example, a type for wide string is needed for "%Ls" and more are
needed to support "%n" with the different possible lenght modifiers.
Luc Van Oostenryck (3):
add builtin type for wide strings
add builtin types for signed char* and short *
add builtin types for size_t*, intmax_t* & ptrdiff_t*
