+ * Replaced setgid() calls with setegid() so that it works with dot
+ * locking on FreeBSD. setegid() should be supported on modern POSIX
+ * systems.
+ *
+ * Revised: Sat Apr 14 17:08:17 PDT 1990 (marvit@hplabs)
* Added hpux hacks to set and reset gid to be "mail" as needed. The reset
* is necessary so inc'ed mail is the group of the inc'er, rather than
* "mail". We setgid to egid only when [un]locking the mail file. This
