 *    endiantest.c

 *    This test was contributed by Bill Janssen.  When used with the
 *    gnu compiler, it allows efficient computation of the endian
 *    flag as part of the normal compilation process.  As a result,
 *    it is not necessary to set this flag either manually or
 *    through the configure Makefile generator.
