// TESTING 'BSLS_LIBRARYFEATURES_HAS_CPP11_UNIQUE_PTR'

// Concerns:
//: 1 'BSLS_LIBRARYFEATURES_HAS_CPP11_UNIQUE_PTR' is defined only when
//: the native standard library defines the 'unique_ptr' class
//: template (in '<memory>').
//
//: 2 If 'BSLS_LIBRARYFEATURES_HAS_CPP11_UNIQUE_PTR' is defined then
//: the related macro
//: 'BSLS_COMPILERFEATURES_SUPPORT_RVALUE_REFERENCES' is also
//: defined.
//
// Plan:
//: 1 When 'BSLS_LIBRARYFEATURES_HAS_CPP11_UNIQUE_PTR' is defined
//: compile code that includes '<memory>' and constructs a
//: 'unique_ptr' object to an 'int'.
//:
//: 2 If 'BSLS_LIBRARYFEATURES_HAS_CPP11_UNIQUE_PTR' is defined confirm
//: that 'BSLS_COMPILERFEATURES_SUPPORT_RVALUE_REFERENCES' is also
//: defined using the associated conditionally initialized global
//: variables. See "Global constants for testing invariants" above.
//
// Testing:
// BSLS_LIBRARYFEATURES_HAS_CPP11_UNIQUE_PTR
