What developer has to really learn streq()? I mean it is pretty obvious
to what it does, as suppose to what bzero and bcopy do. A quick google
on "streq" brings up lots of matches of people who already do this.
Actually, some have "optimized" it with:
#define streq(a, b) (*(a) == *(b) && strcmp(a, b) == 0)
As it fails out if the first character does not match (likely the case
if strings do not match) before it calls the strcmp function.
