 // Methods defined in the 'slots' section (Qt's extention) will be processed
 // by Qt's moc tool (moc.exe on Windows). Unfortunately, preprocessor macros
 // defined for C/C++ are not automatically passed into the moc tool.
 // For example, you need to call the moc tool with '-D' option as
 // 'moc -DENABLE_FOOBER ...' to make the moc tool aware of the ENABLE_FOOBER
 // macro. http://developer.qt.nokia.com/doc/qt-4.8/moc.html
 // So basically we must not use any #ifdef macro in slot declarations.
 // Otherwise, methods enclosed by "ifdef ENABLE_FOOBER" will be simply ignored
 // by the moc tool and |QObject::connect| against these methods results in
 // failure. See b/5935351 about how we found this issue.
