Bug#782824: g++-5: Compilation of application using wxWidgest produces a lot of warnings

[<tonda.misek@post.cz>]

Sorry, here are missing information:

The "minimal" sample is in package wx3.0-examples on path /usr/share/doc/wx3.0-examples/examples/samples/minimal. For the report I used version from wxWidgets web page, but the sample from package wx3.0-examples produce the same warnings, only makefile.unx is missing and source file is gziped. I used command:
g++-5 -c -o minimal_minimal.o -I. `wx-config --cxxflags --unicode=yes --static=no --toolkit=gtk2 --version=3.0` -MTminimal_minimal.o -MF`echo minimal_minimal.o | sed -e 's,\.o$,.d,'` -MD -MP minimal.cpp

For buid you will need also package "wx-common" (it provides wx-config).

Why I thing that it is bug? Personally I am unsure if the bug is in wxWidgets or in GCC, at first I reported it to wxWidgest developers (I am not familiar with the internals of wxWidgets), but they mean that their code is valid: https://groups.google.com/forum/?fromgroups#!topic/wx-dev/MSDyJ6jbRP4
Note that g++-4.9 don't produce these warnings (I understand that it is not important...).

Thank you for your time
TonyMi
