/* machine-specific stuff:
   based on a number of factors in the library stdlib.h, we will try
   to determine what kind of machine/compiler this program is being
   built on.  However, it doesn't always succeed.  However, if you have
   ANSI conforming C, it will probably work.

 we will try to figure out machine type
 based on defines in stdio, and compiler-defined things as well.: */
