I received an email and a patch on Sep 15 2002.  I incorporated the
patch, here is the email.

  Subject: fgetty-0.6: a checkpassword with PAM support

  Hi Felix,

  I put together a checkpassword-pam program. I understand that
  you don't like PAM, but nevertheless it could be useful to
  someone else besides me. It is based on your checkpassword program
  and the routines found in support-pam.c of the checkpassword-pam-0.95
  program.

  Feel free to edit/distribute/(or even ignore it)   :-)

  Thanks for writing/sharing such great non-bloated tools.

To build it, say

  $ make checkpassword-pam

Please note that you can't link checkpassword-pam with the diet libc,
and I could not test the patch because I don't have PAM installed on any
box.
