         print "pi/2 = ", M_PI_2, "\n";
         print "erf(1) = ", erf(1), "\n";
         print "hypot(3,4) = ", hypot(3,4), "\n";

         my $signgam = 0;
         my $y = lgamma_r(-0.5, $signgam);
         print "signgam=$signgam lgamma=$y\n";

       Only tested on AIX 4.2, FreeBSD 4.0, Linux 2.2.16, and Solaris 2.5.1.  May need some more
       functions.
