- * 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 strtok,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.
