Hi, 

I think there is a bug in g++ 4.4 concerning the implementation of auto.
7.1.6.4/7 in N2914

The following program compiles, but it should be rejected by g++.

int main() 
{
    auto i = 10, d = 5.0; // error! shall not compile in C++0x

    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++4.4BugAutoN2914.cpp
g++4.4BugAutoN2914.cpp: In function 'int main()':
g++4.4BugAutoN2914.cpp:4: warning: unused variable 'i'
g++4.4BugAutoN2914.cpp:4: warning: unused variable 'd'
