[Jack-Devel] Jack2 build error - Debian 7 amd64

I just did a git pull from Jack2 on GitHub and tried compiling it on Debian
stable amd64. The build fails. I previously built it on May 25th and it was
fine.

There are lots of error messages similar to the following:

I'm using libsndfile compiled from git on March 21st, which until now hasn't caused a problem.
