* in import.c, #ifdef out references to dynamic loading based on HAVE_DYNAMIC_LOADING * clean out the platform-specific crud from importdl.c. [ maybe fold this function into import.c and drop the importdl.c file? Greg.] * change GetDynLoadFunc's "funcname" parameter to "shortname". change "name" to "fqname" for clarification. * each GetDynLoadFunc now creates its own funcname value. WARNING: as I mentioned previously, we may run into an issue with a missing "_" on some platforms. Testing will show this pretty quickly, however. * move pathname munging into dynload_shlib.c
