As an FYI
On my ubuntu 12.04 system, I am getting many compile errors for threads and mutex api's. It appears the threads API is changing in 2.32. <http://developer.gnome.org/glib/2.31/glib-Deprecated-Thread-APIs.html> This impacts the current threads and mutex calls in gpredict.
Usually they have extended support for old API's but I have never seen such compiler griping before. This issue is just to let folks track it.
