-# - fix all the code that is causing warnings (We are currently working with Joe Stenbrenner from Division Management to have this task outsourced to Bangalore)
-# - re-enable the -Werror flag (see above)
+# - re-enable the -Werror flag after openmrcp compilation warnings are fixed
# - needs to compile/link against the _freeswitch_ sofia libs (see FIXME)
-# - is there an openmrcp dir in the fs tree yet? (see FIXME)
