            Bug ID: 60209
           Summary: Declaration of user-defined literal operator cause
                    error
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

I think that the sample code below should be compiled successfully.

void operator "" "" _x(unsigned long long);

According to C++11 standard 2.2[lex.phases], string literal concatenation
occurs in compilation phase 6 and syntax analysis is performed in compilation
phase 7.
