This is not really mach-o related, but a consequence of the way in which GCC specs substitution works. Unless the libstdc++-v3/.libs and libsupc++/.libs are visible as -Bxxxxx, spec substitution will not work (it's not enough to provide -L). This is done elsewhere (e.g. gnattools), it just needs an appropriate addition to the libcc1/Makefile.in (will try and take a look later in the week, if no-one else gets to it first). Iain
