/* These are the sizes of the standard integer types.  NOTE that these type
 * names have a leading underscore character.  This file will be included
 * (indirectly) by include/stdint.h and typedef'ed to the final name without
 * the underscore character.  This roundabout way of doings things allows
 * the stdint.h to be removed from the include/ directory in the event that
 * the user prefers to use the definitions provided by their toolchain header
 * files
 *
 * These are the sizes of the types supported by the ZiLOG Z8Encore! compiler:
 *
 *   int    - 16-bits
 *   short  - 16-bits
 *   long   - 32-bits
 *   char   - 8-bits
 *   float  - 32-bits
 *   double - 32-bits
 *
 * Pointers:
 *
 *   near pointer - 8-bits
 *   far pointer - 16-bits
 *   rom pointer - 16-bits
