*************************************************************************
*
* "DHRYSTONE" Benchmark Program
* -----------------------------
*
* Version: C, Version 2.1
*
* File: dhry.h (part 1 of 3)
*
* Date: May 25, 1988
*
* Author: Reinhold P. Weicker
* Siemens Nixdorf Inf. Syst.
* STM OS 32
* Otto-Hahn-Ring 6
* W-8000 Muenchen 83
* Germany
* Phone: [+49]-89-636-42436
* (8-17 Central European Time)
* UUCP: weicker@ztivax.uucp@unido.uucp
* Internet: weicker@ztivax.siemens.com
*
* Original Version (in Ada) published in
* "Communications of the ACM" vol. 27., no. 10 (Oct. 1984),
* pp. 1013 - 1030, together with the statistics
* on which the distribution of statements etc. is based.
*
* In this C version, the following C library functions are
* used:
* - strcpy, strcmp (inside the measurement loop)
* - printf, scanf (outside the measurement loop)
