    Work around gtk warnings with gcc 8.0

commit 1f3cf845c4588e787f9b26ad06b05d7cd73326b7
Author: Geert Janssens <geert at kobaltwit.be>
Date:   Wed May 9 17:20:13 2018 +0200

    Work around a conflict between gcc 8.0 and swig 3.0
    
    The swig 3.0 generated python wrappers trigger a warning converted into an error issued
    by gcc 8.0 for using strncpy as follows:
    strncpy(buff, "swig_ptr: ", 10);
    The reason is this call will truncate the trailing null byte from the string.
    This appears to have been fixed in swig master already but that's not released yet
    so let disable the warning when compiling the swig wrappers until it is.
