//: 4 If 'BSLS_LIBRARYFEATURES_HAS_CPP17_SEARCH_OVERLOAD' is *not* set,

//: an expression using the namespace-unqualified name 'search'. If

//: 5 If 'BSLS_LIBRARYFEATURES_HAS_CPP17_SEARCH_FUNCTORS' is *not* set
//: set, we do not test for the possible presence of the 'native_std'

// TESTING 'BSLS_LIBRARYFEATURES_HAS_CPP11_RANGE_FUNCTIONS'
//
// Concerns:
//: 1 The 'BSLS_LIBRARYFEATURES_HAS_CPP11_RANGE_FUNCTIONS' flag is
//: defined when the 'begin' and 'end' function templates are
//: provided by the native standard library.
//:
//: 2 The 'BSLS_LIBRARYFEATURES_HAS_CPP11_RANGE_FUNCTIONS' flag is not
//: defined unless the 'begin' and 'end' function templates are
//: provided by the native standard library.
//
// Plan:
//: 1 Write a test type, 'case13::TestType', that has members 'begin'
//: and 'end', returning a correspondingly defined 'iterator_type'.
//:
//: 2 If the feature macro is defined, explicitly call 'std::begin' and
//: 'std::end' to confirm they exist with a compatible signature.
//:
//: 3 If the feature macro is NOT defined, apply a 'using namespace' to
//: both namespaces 'std' and 'case13', and then call 'begin' and
//: 'end'. The call will be ambiguous and force a compile-time error
//: only if the 'std' functions are also available, indicating that
//: the feature macro should be defined.
