This one is somewhat faster (one less test in the main loop) and
(I think) cleaner. (It does assume tolower(n)==0 iff n==0)

static int strnicmp(const char *s1, const char *s2, int len)
{
/* Yes, Virginia, it had better be unsigned */
unsigned char c1, c2;

while (len) {
c1 = *s1;
s1++;
c2 = *s2;
s2++;
if (c1 != c2) {
c1 = tolower(c1);
c2 = tolower(c2);
if (c1 != c2)
return c1 < c2 ? -1 : 1;
}
if (!c1) return 0;
len--;
}
return 0;
}
