+Subject: [PATCH] native/TexturePacker: fix compilation with gcc 4.6
+
+Kodi itself depends on gcc >= 4.7 due to its use of the C++11 standard.
+When cross-compiling the host gcc currently also needs to be >= 4.7 due
+to the texturepacker tool being needed as native binary to compile
+Textures.xbt for the target system.
+
+Cross-compiling on a system where host gcc is at version 4.6 fails atm
+with this error:
+
+cc1plus: error: unrecognized command line option '-std=c++11'
+make[4]: *** [md5.o] Error 1
+make[4]: *** Waiting for unfinished jobs....
+cc1plus: error: unrecognized command line option '-std=c++11'
+cc1plus: error: unrecognized command line option '-std=c++11'
+
+make[4]: *** [DecoderManager.o] Error 1
+make[4]: *** [XBTFWriter.o] Error 1
+cc1plus: error: unrecognized command line option '-std=c++11'
+make[4]: *** [TexturePacker.o] Error 1
+cc1plus: error: unrecognized command line option '-std=c++11'
+make[4]: *** [decoder/PNGDecoder.o] Error 1
+make[3]: *** [all] Error 2
+make[2]: *** [native/TexturePacker] Error 2
+
+Using this patch the problem is fixed and a working TexturePacker host
+binary is created.
