+ *
+ * Revision 1.5 1999/09/30 23:23:14 netbug
+ * added the TYPE(socklen_t) check to the MCONFIG.in files
+ * question? do I need to update the .cvsignore files to
+ * prevent CVS checking in configure scripts....
+ *
+ * Revision 1.4 1999/03/27 07:42:06 dholland
+ * PAM changes.
+ *
+ * Revision 1.3 1998/03/08 16:51:50 root
+ * grabbed the redhat pam patches and integrated most of it
+ * though I've decided to go with xstrdup as opposed to pam's x_strdup
+ *
+ * Revision 1.2 1997/06/08 19:57:22 dholland
+ * minor fix - don't define __USE_BSD if already defined.
