FWIW, for the historically interested, http://www.freebsd.org/cgi/cvsweb.cgi/src/libexec/rtld-aout/Attic/rtld.c?hideattic=0 indicates this to be working in aout from rev. 1.25, backported to FreeBSD 2.1. I've applied the following patches into Libtool branch-1-5 and HEAD, respectively. Thanks again. Cheers, Ralf branch-1-5: * ltdl.m4 (AC_LTDL_SYS_DLOPEN_DEPLIBS) [ freebsd, dragonfly ]: Set libltdl_cv_sys_dlopen_deplibs to yes.
