Comment 2 for bug 1236086

Ah, sorry. I didn't see that there was a newer version because I found pbzip2 here: http://compression.ca/pbzip2/ and the latest version listed there is the 1.1.6 I used.

Yes, that stack overflow answer does seem like the right answer.

Version 1.1.8 seems to have the same issues:

I changed it to use the type safe version as per that SO post and this took care of the compiler warnings. Here's the diff output for the changes to 1.1.8 to remove the warnings (sorry don't have bzr and doesn't look like something worth installing/learning at this point since it appears to be dying slowly):
