The 'typename refers to the 'other' identifier. Use of
_Alloc::template rebind implies that _Alloc has a nested class
template called rebind. The whole statement is typedefing _Alty to the
type other, declared in the template instantiation rebind<_Ty>, which
is declared in the template parameter _Alloc. So, _Alloc should look
something like:
struct _Alloc
{
template <class SomeType>
struct rebind
{
typedef {some-declaration} other;
};
};

Judging by the header file path name, it's VC++ 7.1 (i.e. the one from
Visual Studio .NET 2003).
