Btw. if you could look at this bugreport as well and provide an 
optimized sincos implementation, it would be appreciated:
http://sourceware.org/bugzilla/show_bug.cgi?id=14412

Just a few comments on your submission:

* Please add a copyright header.
* Instead of defining EDOM, I suggest to:
#include <bits/errno.h>

* For your comments, follow the usual style - with two spaces after "." 
or "?" - and no space before

Could you make those changes and resubmit, please?

Thanks,
Andreas
