None of the libquadmath functions can throw or serve as cancellation points, therefore we should allow optimizers to assume that. Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk? 2011-01-07 Jakub Jelinek * quadmath.h (__quadmath_throw, __quadmath_nth): Define. Use it for all prototypes.
