What is the meaning of Anicca and Anatta?

Most of the English translation I read, Anatta is translated as not-self and Anicca as impermanence. However many Sri Lankan Buddhist monks do not agree with this translation. They say it is a miss translation by Buddhagosha. According to many Buddhist monks, it appears, Anicca means our inability to control the five aggregate. Anatta means the futile nature of the five aggregate. Is this true?
