Subject: [PATCH v2 03/10] gethostbyname: check for libnsl (Solaris support)
Date: Mon, 5 Nov 2012 11:01:56 -0800 [thread overview]
Message-ID: <1352142123-18286-4-git-send-email-blakej@foo.net> (raw)
In-Reply-To: <1352142123-18286-1-git-send-email-blakej@foo.net>
Add a check to "configure" to see whether -lnsl is needed for programs
that are using gethostbyname(). This change also adds the file
"compat/check_ghbn.c", which configure uses to perform its check.
