What Unit Testing Framework do you use for C?
audidude: I love the g_test_* stuff in libglib.  It can handle various types of tests (slow, fast, perf, etc).  Runs them in sub processes.  Generates reports. Easy to use.  I also love the assertion helpers included for easy readability of the errors.Docs: http://library.gnome.org/devel/glib/stable/glib-Testing.html
