Link error with __builtin_sincosf()

This may be more of a gcc question, but I'm having trouble with the __builtin_sincosf() intrinsic. I get a link error that '_sincosf' is an undefined symbol. For example, try compiling:

void mysincosf(float x, float* s, float* c) {
    __builtin_sincosf(x, s, c);
}

This happens on both Intel and PPC platforms. Any ideas?  (For that matter, is there a compiler intrinsic that calculates reciprocal square root?)

Thanks, Ben
