Dear Maintainer,

Building Audacity with gcc 4.8 clutters the build log with these warnings:

/usr/include/wx-2.8/wx/buffer.h: In member function 'void wxMemoryBuffer::AppendByte(char)':
/usr/include/wx-2.8/wx/debug.h:194:43: warning: typedef 'wxDummyCheckInt' locally defined but not used [-Wunused-local-typedefs]
     #define wxFORCE_SEMICOLON typedef int wxDummyCheckInt
                                           ^
/usr/include/wx-2.8/wx/debug.h:224:9: note: in expansion of macro 'wxFORCE_SEMICOLON'
         wxFORCE_SEMICOLON /* just to force a semicolon */
         ^
/usr/include/wx-2.8/wx/debug.h:233:38: note: in expansion of macro 'wxCHECK2_MSG'
 #define wxCHECK_RET(cond, msg)       wxCHECK2_MSG(cond, return, msg)

         wxCHECK_RET( m_bufdata->m_data, wxT("invalid wxMemoryBuffer") );
         ^
