No trouble.  I'm surprised we never did anything about it, TBH.

Reviewing our buildfarm members, it looks like none of the current
Solaris or illumos/OpenIndiana animals use --with-pam, which is a
bit sad but explains why we don't see any warnings in the farm.
And I guess end users have just ignored the warning so far.
But we'll have to up our game if GCC is going to start making this
an error by default.
