AFAIK, Cephes works on a wide range of platforms, so I don't think it would break anything. Merely installing the package should just work, using it by default is another matter. :) I am not sure what the speed of the cephes implementation is compared to that of the C library though. The float evaluations are used for plotting, so any slow down in the numerical approximation of these functions will degrade plotting performance significantly. On another note, if Cephes is only included for the evaluation of these few functions, I am not convinced it should be shipped in the standard distribution. There are quite a few libraries already in Sage, which have this capability. For example, can't we just use GSL to evaluate gamma on Cygwin?
