  and prefer uninstalled libraries to installed ones
* Library paths that are in the system default run-time search path

  BSD/OS 4.x and NetBSD
* In order for libtool to attempt to link a shared library (dll) on win32
  platforms, you must pass the -no-undefined flag to libtool in link mode.
* The path to GNU ld now works on cygwin-b18 to cygwin-b20.2 at least.
* Support for IRIX library versioning.
* New demos and tests

  Be aware that libltdl is only known to work on a few platforms such as
  GNU/Linux and Solaris2.  Some mdemo tests are known to FAIL on several
