+wchar.h: only include other headers if _FORTIFY_SOURCE is enabled
+
+unexpectedly including other headers can cause problems with
+sensitive/brittle code, particularly with alternative compilers
+(clang) which are already operating on the margins of what's
+supported/expected by some projects.
+
+having a way to almost entirely short-circuit these headers (by
+disabling _FORTIFY_SOURCE) is therefore important.
