   I tried sending this directly to Angel Li@flipper.miami.edu, but the network
   was down.

   The following program:

   #include <math.h>
   #include <stdio.h>
   main()
   {
	   printf("sqrt(2): %g\n", sqrt(2));
   }

   dies at the link stage because the linker needs SQRT__FD and can't find it.
   This program runs fine under VMS/GCC.  Were we supposed to get the full
   Unix g++ distribution and recompile the source, say, using the VMS/g++
   executable?  Also, we stole math.h from the VAX C header directory.

You need to do this oin your program:

extern "C"
{
#include "math.h"
}
