* replace ifdefs against __SVR4 and __linux__ with DIRENT_MISSING_D_NAMLEN;
it's more portable and more obvious * remove the mkgmtime() && HAVE_TIMEGM stuff: a) why should netbsd have to define HAVE_TIMEGM to compile cleanly? b) foreign compiles of ftp should just be linked with working timegm function a more portable version of this ftp client will be released as a 3rdparty product; no use polluting our code with half-baked attempts...
