Correct signature of / detect presence of Container::reserve()

http://stackoverflow.com/questions/14882588/correct-signature-of-detect-presence-of-containerreserve

This works for C being std vector but not for the unordered containers e.g. std unordered_set . The reason is that reserve.. std vector but not for the unordered containers e.g. std unordered_set . The reason is that reserve is a direct member function.. is a direct member function of std vector but for the unordered containers it is inherited from a base class i.e. its signature..
