Compile error on Solaris 11.2 (tests for inet_pton and inet_ntop fail)

["Venturini, Andreas" <andreas.venturini@gmail.com>]

Hello,

I am trying to compile tarsnap on a Solaris 11.2 box. For some reason 
the compile script fails to properly detect both, inet_pton and inet_ntop.

See my comment on the following gist for console output: 
https://gist.github.com/robinsmidsrod/ae6ca91a166ef5313048

Is there someone running tarsnap with Solaris 11.2 who can help with this?

Thanks,

Andreas
