           Summary: gcc prints warning "ref-qualifiers only available with
                    -std=c++0x or -std=gnu++0x" for operator&
    Classification: Unclassified
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3

minimal test file demonstrating the problem

gcc from 4.8 svn branch prints an incorrect warning about "ref-qualifiers only
available with -std=c++0x or -std=gnu++0x" for a line like

if (bool(windowState() & Enum1) == true)

where the & is actually an operator& for the class returned by windowState().
Attached code demonstrates the problem.

I didn't have this problem with gcc 4.8.0.
