Subject: 	removed all knowledge about dlopen() and friends from the
X-Git-Tag: release_0_1_0~847
X-Git-Url: http://www.project-moonshot.org/gitweb/?a=commitdiff_plain;ds=sidebyside;h=b1ca16f195d5a55db11f29446602f0920f525ae8;p=freeradius.git

	removed all knowledge about dlopen() and friends from the
	configuration process.  We now rely on libltdl to do that work
	for us.

	The HOPE is that this change will make the server portable to
	systems with bizarre shared library implementations.
