>Description:
	As currently declared, the pam_* functions don't guarantee
	the read-onlyness of the passed in data, even where no
	modifications could happen.

	The declarations also differ from those used of Solaris
	and Linux, leading to increased porting burden of 3rd-party
	PAM-modules (such as Samba's winbind).

	It is possible, that a newer version of OpenPAM will bring
	in these changes, but we can update the headers (without
	functional changes) now to introduce the updated API and
	ease the porting efforts.

>How-To-Repeat:
>Fix:

	The up-to-date patch can be found at

		http://aldan.algebra.com/~mi/pam-const.patch

	or -- color-coded -- at:

		http://aldan.algebra.com/~mi/pam-const.patch.html

	It does not, at the moment, touch the relevant man-pages. These
	will be updated soon, but testing/review of the code can begin
	now.

	The changes only add const-ness here and there -- no functional
	changes.
