Subject: 	* t_walk_rtree.c (main): Declare as returning int
X-Git-Tag: krb5-1.3-alpha1~2054
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=872a18cb0cdec1de6b40772a6938f602eff8f844;p=krb5.git

	* t_walk_rtree.c (main): Declare as returning int

	* get_in_tkt.c (_krb5_conf_boolean): Declare as taking a const char *

	* str_conv.c (krb5_timestamp_to_string): Work around gcc's warning
	that %c format in strftime might return only two digits for the
	year.

	* mk_safe.c, rd_rep.c, send_tgs.c: Remove unused goto label.

	* kdc_rep_dc.c (krb5_kdc_rep_decrypt_proc): Remove code with no
	effect.

	* init_ctx.c: Make krb5_brand[] look used.

	* chpw.c, decode_kdc.c, decrypt_tk.c, enc_helper.c, get_creds.c,
	get_in_tkt.c, gic_keytab.c, gic_pwd.c, preauth2.c, vfy_increds.c:
	Add parentheses around assignment used as truth value
