commit 900d17acb95f1becfc46656a12c107336c027ef7
Author: Michael Adam <obnox at samba.org>
Date: Tue Feb 26 13:24:54 2008 +0100
libreplace: Add tests for connect and gethostbyname.
Provide dummy replacements when a function isnt found.
The functions are also searched for in certain libraries,
and variables SOCKET_LIBS and NSL_LIBS are set accordingly.
One purpose of this is to fix the getifaddrs tests on
systems where e.g. the socket calls require special libs
for linking.
