Subject: fix t_prf test code properly
X-Git-Tag: krb5-1.8-alpha1~451
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=0ef1ec87f3996d995cb4dc03223a1474b2064e5f;p=krb5.git

fix t_prf test code properly

Correction to patch in r22364: "i" was used in two places, one of
which required an int-sized value and the other of which required a
size_t.  Instead of changing the type, split the two uses into
separate variables.
