Update to 1.0:

	Changes made between 0.6.4.1 and 1.0 (2005/05/26).

Corrected the source code to not break C strict aliasing rules (this
only affected auth_pam.c).

With Sun PAM (Solaris, HP-UX), insist on only one PAM message per call
to the conversation function because of differences in the layout of
the "msg" parameter.

Bumped the default limits to values that are way too high for most
systems (I'm sure these will still be insufficient for some, though,
but hopefully those systems actually got experienced sysadmins).
Added comments suggesting that these defaults be decreased on
particular installs.
