With the intoduction of the statement type enum came a prefix clash. As "st" makes sense for "statement type", I decided that "storage class" should be "sc". Although there haven't been any problems as of yet, I decided it would be a good idea to clean up the clash now. It also helps avoid confusion (I was a bit surprised after working with st_assign etc to be reminded of st_extern etc).
