           Summary: Incorrect "non-lvalue in unary `&'" error
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: timb@bluearc.com
                CC: gcc-bugs@gcc.gnu.org
 GCC build triplet: i386-linux
  GCC host triplet: i386-linux
GCC target triplet: i386-linux

This code:

void foo(int x)
{
    static_cast<const unsigned int&>(x);
}

gets:

test.cpp:3: error: non-lvalue in unary `&'

AFAICT there is nothing wrong with it, and it compiles fine before 3.3. (And 
what unary `&'?)
