strcpy fu**ing easy

While trying to optimize some c code I had a look at the strcpy.c file and was astonished what to see there:

do
 {
   c = *s++;
   s[off] = c;
 }
while (c != '\0');

This is pretty much it. Some boundary checks. But THAT is it. And nearly all the files in glibc/string are like that.

update: (thx to Edd) the OpenBSD way of doing it

char *
strcpy(char *to, const char *from)
{
      char *save = to;

      for (; (*to = *from) != '\0'; ++from, ++to);
      return(save);
}
