commit 2ade088e991102f642e20a3d20239bf8b2b52633
Author: Raymond Toy <toy.raymond at gmail.com>
Date:   Sat Jul 26 09:00:35 2014 -0700

    Some cleanup of the trig code.
    
     * code/exports.lisp:
       * Export %ieee754-rem-pi/2 and %sincos.
     * code/irrat.lisp:
       * Remove some conditionalization that is always true now.
     * compiler/float-tran.lisp:
       * %sincos is exported so we don't need the package qualifier.
