- * I am not very proud of this code.  It makes use of a possibly ill-
- * defined pamh pointer to call pam_strerror() with.  The reason that
- * I was sloppy with this is historical (pam_strerror, prior to 0.59,
- * did not require a pamh argument) and if this program is used as a
- * model for anything, I should wish that you will take this error into
- * account.
