According to ISO/IEC 14882 6.4-3, the following snippet is ill-formed:

if (int x = 1)
{
  int x = 2; // redeclaration of x
}

Yet the g++ versions that come with Fedora Core 3 accept it.
Specifically, these versions are:

gcc version 3.3.4 20040817 (Red Hat Linux 3.3.4-2)
gcc version 3.4.2 20041017 (Red Hat 3.4.2-6.fc3)
gcc version 4.0.0 20041019 (Red Hat 4.0.0-0.8)

Note this is the full testcase:

{
if (int x = 1)
{
  int x = 2; // redeclaration of x
}
}

Confirmed,  This is related to PR 2288.
