the configure script checks for openldap and friends and we link with those
libs just like we link all other third party libraries, and we no longer

just before this commit, just in case.

fixed warning with gcc 4.x (hopefully); dynamincally imported UseAccurateCaseForPaths() for CLIB port to be stonetime-compatible (NW 3.x).
