I'm not a lawyer, but my understanding of the license is that you
cannot in general link to GPL code without making the whole binary
fall under GPL. The LGPL allows a program to link to it without
affecting the license of the program, though.
You can however have your non-GPL code execute a separate GPL binary
without affecting the legal state of your own code. The important part
is that the programs are kept separate.
