This seg faulted for me due to an infinite recursion in some of the
functions (e.g. cos, fabs) on g++ 2.96.  When I replaced your
namespace std with something else, then it worked.  (Other than domain
errors from functions that didn't like an argument of 2.)

For this reason and generally being a good namespace citizen, I think
putting things in namespace std is probably a bad idea.  What about
instead using some other namespace which can be an alias to std for
well behaved cmath headers and can include what you've written for
non-compliant compilers?
