Here's a patch so that pam_access can compile on Solaris (and probably on
other systems too).

====================== snip =======================

My guess is that the original "gethostname()" declaration had been to
suppress a warning (not error) message from a compiler on one particular
OS (would I be wrong in guessing Linux?) as a supposed cure.

But for systems which have the expected declaration in the expected place,
which might be of a slightly different form, this "cure" is worse than
the illness and causes compiler errors.

So my patch above simply, in effect, removes that declaration. I leave it
to you to decide whether to do it "as is" (which at least leaves for
future generations an indication of why the declaration was poor) or
simply to delete the original lines.

Hope that helps.
