commit 3533a13a8cc53e43a7c4d7d27b3e6b8bcc004672
Author: Raymond Toy <toy.raymond at gmail.com>
Date:   Fri Jul 25 22:17:11 2014 -0700

    Rename sin/cos/tan/sincos so we don't collide with libm.
    
    Update def-math-rtn to allow specifying the C function name and the
    lisp function name so we can use def-math-rtn with the new trig
    functions.
