// This file contains definitions to figure out the size of _HOST_ data types.
// This file is important because different host OS's define different macros,
// which makes portability tough.  This file exports the following definitions:
//
//   [u]int(32|64)_t : typedefs for signed and unsigned 32/64 bit system types
//   [U]INT(8|16|32|64)_(MIN|MAX) : Constants for the min and max values.
//
// No library is required when using these functinons.
