// Libsim provides fast, mostly host emulated IO only supported by

// file support) mostly done by the TigerSHARC target that is supported
// by the emulator and simulator. Libio together with libsim is the
// default used, but if __USING_LIBSIM is defined only libsim will be used.
//   From the driver command line, use options,
//          "-flags-link -MD__USING_LIBSIM=1"
//   in the IDDE, add -MD__USING_LIBSIM=1 to the linker additional

// The define __WORKAROUNDS_ENABLED if set will indicate that the
