This macro detects support for the C++11 '= delete' construct.  Here is the

#   Check whether the C++11 '= delete' syntax, for suppressing undesired
#   implicit methods, is supported.  If it is, the macro DELETE_METHOD is
#   defined to '= delete'; otherwise it is defined to nothing.  Thus, you
#   can write
#     class foo {
#       ...
#     private:
#       foo(foo const&) DELETE_METHOD;
#     };
#   to delete the 'foo' copy constructor or fall back to the idiom of
#   a private undefined method if the compiler doesn't support this.
#   Does not test '= delete' on a template specialization.
#   Does not ensure that the compiler is in C++11 mode.
