//
// LWG3869 deprecates the UNIX STREAMS macros and enum values.
// This makes the code clumbersome:
// - the enum value is deprecated and should show a diagnostic,
// - the macro is deprecated and should _not_ show a diagnostic in this
// context, and
// - the macro is not always available.
// This leads to the odd pushing and popping of the deprecated
// diagnostic.
