gcc interprets C++0x initialization construct as function declaration

[Nathan Ridge]

Hello,

For the following code:

struct S
{
    int a;
    float b;
};
struct T
{
    T(S s) {}
};
int main()
{
    T t(S{1, 0.1}); // ERROR HERE
}

gcc 4.6 trunk gives the following errors (with the --std=c++0x option):

decl.cpp: In function 'int main()':
decl.cpp:14:10: error: expected ')' before '{' token
decl.cpp:14:10: error: a function-definition is not allowed here before '{' 
token
decl.cpp:14:18: error: expected primary-expression before ')' token
decl.cpp:14:18: error: expected ';' before ')' token

It seems gcc is interpreting the statement as a function declaration.

Is this the desired behaviour?

Regards,
Nate.
