Subject: [PATCH] configure: test whether -lresolv is needed
Date: Sun, 7 Jun 2009 07:40:29 +0200 [thread overview]
Message-ID: <20090607054028.GE5140@gmx.de> (raw)
In-Reply-To: <m3y6s54y8g.fsf@localhost.localdomain>
Check if -lresolv is needed for hstrerror; set NEEDS_RESOLV
accordingly, and substitute in config.mak.in.
