// RUN: %clang_cc1 -fsyntax-only %s
// This is a test for an egregious hack in Clang that works around
// issues with GCC's evolution. libstdc++ 4.2.x uses __is_pod as an
// identifier (to declare a struct template like the one below), while
// GCC 4.3 and newer make __is_pod a keyword. Clang treats __is_pod as
// a keyword *unless* it is introduced following the struct keyword.
template<typename T>
struct __is_pod {
__is_pod<int> ipi;
// Ditto for __is_same.
template<typename T>
struct __is_same {
__is_same<int> isi;
// Another, similar egregious hack for __is_signed, which is a type
// trait in Embarcadero's compiler but is used as an identifier in
// libstdc++.
struct test_is_signed {
static const bool __is_signed = true;
bool check_signed = test_is_signed::__is_signed;
#if __has_feature(is_pod)
# error __is_pod won't work now anyway
