The following fails to compile:
template<class T>
class Foo {
// The "friend" declaration below causes fialure with
// error: using template type parameter `T' after `class'
friend class T;
};
class Bar {
};
int
main(int, char**)
{
Foo<Bar> foo;
return 0;

It was supported by the other compilers I use (MS and Sun), and it seemed like such an obvious thing to want to do, and I didn't think anyone would want explicitly to exclude it, so I didn't check the standard. I'm *very* sorry to have wasted your time. FWIW, I discovered a workaround at http://www.byte.com/documents/s=9162/cujexp0312wilson2/ -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24629 ^ permalink raw reply [flat|nested] 7+ messages in thread
