*int _stricmp(dst, src), _strcmpi(dst, src) - compare strings, ignore case

*Purpose:
* _stricmp/_strcmpi perform a case-insensitive string comparision.
* For differences, upper case letters are mapped to lower case.
* Thus, "abc_" < "ABCD" since "_" < "d".
*
*Entry:
* char *dst, *src - strings to compare
*
*Return:
* <0 if dst < src
* 0 if dst = src
* >0 if dst > src
