QList with "local type"

Code:

---

#include <QList>
 
int main(int , char ** )
{
    struct Foo {
        int bar;
    };
 
    QList<Foo> foo;
    return 0;
}

This short program fails to compile for me (using gcc-4.1.0):

prog.cc: In function 'int main(int, char**)':
prog.cc:9: error: 'main(int, char**)::Foo' uses local type 'main(int, char**)::Foo'
prog.cc:9: error: trying to instantiate 'template<class T> class QList'
prog.cc:9: error: invalid type in declaration before ';' token

I can get it to compile by declaring the struct outside the method were it will be used, but since I only need it on one method it feels natural to declare it there.

Not sure if this is a Qt problem or a gcc problem. Is there anyone who knows why you can't make a list of a locally declared struct?

Somewhere I found this -

C++ Standard 14.3.1.2
A local type, a type with no linkage, an unnamed type or a type compounded from any of these types shall not be used as a template-argument for a template type-parameter.
