/**********************************************************************
  VM Considerations

  The VM can not use the standard system headers because we aren't really
  using the compiler they were meant for.  We use bg_lib.h which contains
  prototypes for the functions we define for our own use in bg_lib.c.

  When writing mods, please add needed headers HERE, do not start including
  stuff like <stdio.h> in the various .c files that make up each of the VMs
  since you will be including system headers files can will have issues.

  Remember, if you use a C library function that is not defined in bg_lib.c,
  you will have to add your own version for support in the VM.
