I'm creating a commercial program for Windows using CodeBlocks + MinGW + wxWidgets. It's simple Windows application for engineering calculations. In my project unmodified C++ libraries are used. wxWidgets was compiled by myself with the command line:
mingw32-make.exe -f makefile.gcc USE_XRC=1 SHARED=1 MONOLITHIC=1 UNICODE=1 USE_OPENGL=1 BUILD=release -std=gnu++11
As a result my application contains the following files:
myprogram.exe
libgcc_s_dw2-1.dll
libstdc++-6.dll
libwinpthread-1.dll
wxmsw315u_gcc_custom.dll
wxmsw315u_gl_gcc_custom.dll
some data files...
How can I correctly (in terms of license) include these library files in my distribution?

From wxWidgets point of view, you don't need to do anything special, the
licence allows you to "distribute [binaries of wx] under your own terms".
We appreciate when the application developers give credit to wxWidgets, but
this is not at all a requirement. For MinGW run-time DLLs you need to check
which licence are they under, but I believe that they use LGPL and there
could be a separate exception for the run-time files in any case, so I
don't think this imposes any actual restrictions neither, but in any case,
this is not at all related to wx, so if you have any questions about this,
you should ask gcc/GNU people.
