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 {
    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.
