00007    Declaration for single-call sincos() function, which stuffs the sine
00008    and cosine of an angle in radians into the second and third pointer
00009    args, respectively.

00011    Some platforms may already have this defined (it's not ANSI). See
00012    sincos.c for how to access sincos() in cases where there is software
00013    support, hardware support, or neither.
