BSLS_DEPRECATE_IS_ACTIVE

Expand to an expression evaluating to true in a preprocessor context if deprecations are being enforced for the specified version M.N of the specified UOR U, and expand to an expression evaluating to false otherwise. Deprecations will be enforced for version M.N of UOR U if: * BB_SILENCE_DEPRECATIONS_<U><M><N> has not been defined in this translation unit, and * BB_SILENCE_DEPRECATIONS_FOR_BUILDING_UOR_<U> has not been defined in this translation unit, and * One of the following holds true: - BB_WARN_ALL_DEPRECATIONS_FOR_TESTING_ONLY has been defined, or - An explicit deprecation threshold has been defined for UOR U and that threshold is greater than or equal to version M.N, or - An explicit deprecation threshold has not been defined for UOR U, the versioning package for UOR U defines <U>_VERSION_MAJOR and <U>_VERSION_MINOR, and the version so designated is greater than version M.N.
