-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.
