Well Boris looks like that did it. It was compiling correctly before,
I just typo-ed in a '=3D', I would pray that g++ would not allow that. I
now have raw DER's going to a file so this last part of my project is
complete! Now just have to do a little gluing together and I should be
just fine.

Thank you for your continued help, I really appreciate it. I would
have spend weeks looking through Mozilla's DOM before I came to a
solution close to this. Have a good one sir, Go Navy.
