+dnl If boost (prior to 1.57) was built without c++11, it emulated scoped enums
+dnl using c++98 constructs. Unfortunately, this implementation detail leaked into
+dnl the abi. This was fixed in 1.57.
+
+dnl When building against that installed version using c++11, the headers pick up
+dnl on the native c++11 scoped enum support and enable it, however it will fail to
+dnl link. This can be worked around by disabling c++11 scoped enums if linking will
+dnl fail.
+dnl BOOST_NO_SCOPED_ENUMS was changed to BOOST_NO_CXX11_SCOPED_ENUMS in 1.51.
