Comment (by michel):

 gcc has
 {{{
 #pragma GCC diagnostic ignored "-Wxxxx"
 }}}
 but, before gcc 4.6, the following is not supported.
 {{{
 #pragma GCC diagnostic push
 #pragma GCC diagnostic ignored "-Wxxxx"
 #pragma GCC diagnostic pop
 }}}
 So we cannot restore the user's warning conditions.

 Another way to disable warnings is add
 {{{
 #pragma GCC system_header
 }}}
 Adding this pragma into `result_of.hpp` or `result_of_iterate.hpp` removes
 the warning.
