<div>
<pre>The code comes from boost typeof:
template <typename ID, typename T = int>
struct msvc_extract_type;
template <typename ID>
struct msvc_extract_type<ID, int> {
template <bool> struct id2type_impl;
};
template <typename ID, typename T>
struct msvc_extract_type
: msvc_extract_type<ID, int> {
template <>
struct id2type_impl<true> // VC8.0 specific bugfeature
{};
};
clang errors while Visual C++ 2013 (from the comment, all the way from VC 8...)
accepts it, so it should be a warning instead of error when Microsoft
extensions are enabled.</pre>
