// 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:
//
//   int64_t       : is a typedef for the signed 64 bit system type
//   uint64_t      : is a typedef for the unsigned 64 bit system type
//   INT64_MAX     : is a #define specifying the max value for int64_t's
//
// No library is required when using these functinons.

// happening when system headers or C++ STL headers include stdint.h before
// we define it here, we define it on the g++ command line (in Makefile.rules).
