1/* Test program for string(3) routines.
2 *
3 * Slightly modified from Henry Spencer's original routine.
4 * - incorporates semantic changes per the ANSI standard (original tests
5 * can be recovered by defining the symbol NOT_ANSI while compiling,
6 * except for the change of memcpy() to memmove()).
7 * - makes additional tests of functions on unaligned buffers and strings.
