All programs that refer to the internal structure of the FILE object can't be compiled from now on. std{in,out,err} doesn't refer __sF[] now, but the hidden __sF along with __srget and __swbuf symbols are kept temporarily to make our transition easier. The shared library versions are bumped for libc and all the other libraries that refer to std{in,out,err}. Those who normally build from source are strongly encouraged to use a snapshot upgrade to cross the bumps.
