Richard,
Darwin10 should benefit from a libtool update since Peter O'Gorman's
patch to leverage the new -force_load flag in Snow Leopard's ld...
http://git.savannah.gnu.org/cgit/libtool.git/commit/?id=4ad8b63bd1069246c540ba2973da967fe7b68c9c
is supposed to provide the equivalent to the linux ld's --whole-archive.
-force_load path_to_archive
Loads all members of the specified static archive library. Note: -all_load forces all members
of all archives to be loaded. This option allows you to target a specific archive.
This should eliminate the issues with missing object files when libtool's
convenience archives are used...

Actually, I would be very interested in testing the proposed libtool patch
to verify that this new change works as advertised (coupled with the pending
dsymutil fixes...http://gcc.gnu.org/ml/gcc-patches/2009-12/msg00094.html
and http://gcc.gnu.org/ml/gcc-patches/2009-12/msg00096.html). This should finally
fix up darwin for properly debugging in libstdc++ and libjava which both
use such libtool convenience archives.
