- * On a 486 or Pentium, we are better off not using the
- * byte string operations. But on a 386 or a PPro the
- * byte string ops are faster than doing it by hand
- * (MUCH faster on a Pentium).

-/*
- * This string-include defines all string functions as inline
- * functions. Use gcc. It also assumes ds=es=data space, this should be
- * normal. Most of the string-functions are rather heavily hand-optimized,
- * see especially strsep,strstr,str[c]spn. They should work, but are not
- * very easy to understand. Everything is done entirely within the register
- * set, making the functions fast and clean. String instructions have been
- * used through-out, making for "slightly" unclear code :-)
