Defines

Default type sizes.

These defaults are reasonable for most 16/32bit machines.

Some of these macros may be overridden by CPU-specific code above.

ANSI C requires that the following equations be true: 

   sizeof(char) <= sizeof(short) <= sizeof(int) <= sizeof(long)
   sizeof(float) <= sizeof(double)
   CPU_BITS_PER_CHAR  >= 8
   CPU_BITS_PER_SHORT >= 8
   CPU_BITS_PER_INT   >= 16
   CPU_BITS_PER_LONG  >= 32
#define SIZEOF_CHAR   1
#define SIZEOF_SHORT   2
#define SIZEOF_INT   2
#define SIZEOF_LONG   4
#define SIZEOF_PTR   2
#define SIZEOF_SIZE_T   2
#define CPU_BITS_PER_CHAR   (SIZEOF_CHAR * 8)
#define CPU_BITS_PER_SHORT   (SIZEOF_SHORT * CPU_BITS_PER_CHAR)
#define CPU_BITS_PER_INT   (SIZEOF_INT * CPU_BITS_PER_CHAR)
#define CPU_BITS_PER_LONG   (SIZEOF_LONG * CPU_BITS_PER_CHAR)
#define CPU_BITS_PER_PTR   (SIZEOF_PTR * CPU_BITS_PER_CHAR)
