Hi, 

I think there is another bug in g++ 4.4 concerning the implementation of auto
with direct and copy initialization 7.1.6.4/3 in N2914

The following program should compile, but is rejected by g++.

int main() 
{
    auto v1 = 1; // copy initialization syntax
    auto v2(2); // direct initialization syntax

    return 0;
}

$ /opt/gcc-4.4/bin/g++ -v
Using built-in specs.
Target: i686-pc-cygwin
Configured with: ./configure --prefix=/opt/gcc-4.4
Thread model: single
gcc version 4.4.0 (GCC)

$ /opt/gcc-4.4/bin/g++ --std=c++0x -Wall g++4.4Bug2AutoN2914.cpp
g++4.4Bug2AutoN2914.cpp: In function 'int main()':
g++4.4Bug2AutoN2914.cpp:5: error: 'v2' has incomplete type
g++4.4Bug2AutoN2914.cpp:4: warning: unused variable 'v1'
g++4.4Bug2AutoN2914.cpp:5: warning: unused variable 'v2'
