Comment:

 Vicente,

 I'm having a problem with this patch.  My gcc 4.53 compiler gives the
 error message:

 "noncopayable:: declared with non-public access cannot be defaulted in the
 class body"

 Which seems to make some sense to me.  My copy of the standard (section
 8.4.2) says
 "If it[the function] is explicitly defaulted on its first declaration, —
 it shall be public,"
 As usual the standard text is somewhat convoluted, but that what it says
 to me. I'm
 not sure why the test passes.  The macro name
 (BOOST_NO_DEFAULTED_FUNCTIONS used to condition this code has been marked
 as deprecated in favor of a new one (BOOST_NO_CXX11_DEFAULTED_FUNCTIONS) i
 don't know if that might be related.
