  • New preprocessor constructs, __has_include + and __has_include_next, to test the availability of headers + have been added.
    + This demonstrates a way to include the header <optional> + only if it is available:
    +
    +#ifdef __has_include
+#  if __has_include(<optional>)
+#    include <optional>

+#    define have_optional 1
+#    define experimental_optional
+#  else
+#    define have_optional 0
+#  endif
+#endif
+
    + The header search paths for __has_include_next + and __has_include_next are equivalent to those + of the standard directive #include + and the extension #include_next respectively. +
