Use dlsym() in preference to NSLookupSymbolInModule() on Darwin, if available. ChangeLog addition: 2011-08-24 Aidan Kehoe <kehoea@parhasard.net> * configure.ac: On OS X, if dlopen() is available in dlfcn.h, use it in preference to dyld; the latter API is deprecated. Move DLSYM_NEEDS_UNDERSCORE together with HAVE_DLYD, it's not needed if the dlsym() and dlopen() APIs are being used. Define REALPATH_CORRECTS_CASE, DEFAULT_FILE_SYSTEM_IGNORE_CASE in this file, don't define them in terms of HAVE_DYLD in src/config.h.in. * configure: Regenerate. src/ChangeLog addition: 2011-08-24 Aidan Kehoe <kehoea@parhasard.net> * config.h.in: Move REALPATH_CORRECTS_CASE, DEFAULT_FILE_SYSTEM_IGNORE_CASE to ../configure.ac rather than implementing them in terms of HAVE_DYLD here.
