Quoth http://boost.org/libs/array/array.html :

> Could "{ ... }" be used portably instead of "{ { ... } }" to
> initialize values? 
> 8.5.1 (11) of the Standard seems to allow it; however, gcc
> 2.95.2 prints a warning message.

C:\Temp>type array.cc
#include <iostream>
#include <boost/array.hpp>
using namespace std;
using namespace boost;

int main() {
    array<int, 4> a = { 15, 20, 25, 30 };

    cout << a[0] << " " << a[1] << " " << a[2] << " " << a[3] << endl;
}

C:\Temp>g++ --version
g++ (GCC) 3.3 (mingw special 20030514-1)

C:\Temp>array
15 20 25 30

C:\Temp>

I would therefore conclude that 2.95.2 sucks and 3.3 conforms more closely
to the Standard (of course, 2.95.2 is free to /warn/ about anything it
likes, but that doesn't stop it from sucking).
