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

#define wxCHECK_RET(cond, msg) wxCHECK2_MSG(cond, return, msg)

/usr/include/wx-2.8/wx/buffer.h:289:9: note: in expansion of macro 'wxCHECK_RET'
wxCHECK_RET( m_bufdata->m_data, wxT("invalid wxMemoryBuffer") );

Please apply the attached patch to silence the warnings.
PS: The patch is already forwarded to upstream:
http://trac.wxwidgets.org/ticket/16028
