Jack, based on the above, can this be closed now? Thanks.

Ralf,
Yes. Current gcc trunk always ends up with -lSystem last for the gcc build
itself. I had been considering creating a version_compare_remove_outfile spec
function to handle all the other symlinks of libSystem but this is impossible
to implement. Closing as fixed.

if we could get Java and libquadmath to intercept the new
LINK_GCC_C_SEQUENCE_SPEC
instead of re-writing the *lib sequence
it would give us a little more room to maneuver.
.. as it is when another part of the complier hijacks the *lib sequence it
happens too late for the target to intervene -- anything inserted as a '-l*' is
untouchable at that stage.
if we have the option to re-write from the start of LINK_GCC_C_SEQUENCE_SPEC
we're in with a chance...
otherwise .. the only solution then is to apply target-specific stuff in the
lib/java builds.

Iain,
I was referring to the conceptual problems of creating a
version-compare-remove-outfile spec function. For any given OS release there is
a different set of symlinks for libSystem which are visible to the compiler
regardless of the setting of -mmacosx-version-min=. So one would really have to
have version-compare-remove-outfile look only at the running OS version to
decide properly which symlinks are present to prune.

The remove_outfile.diff patch has the additional advantage of also eliminating
the gcc.dg/torture/builtin-math-7.c failures.

These patches also appear to clean up the linkages on libstdc++.6.dylib and
libgfortran.3.dylib so that now libSystem is properly at the end of the
linkage. It will be interesting to see if these patches help eliminate the
random failures I have seen with...
FAIL: tr1/2_general_utilities/shared_ptr/thread/default_weaktoshared.cc
execution test
in the libstdc++ testsuite.

The combination of the remove_outfile.diff and libjava_lm_lpthread_cleanup.diff
patches eliminates the incorrect linkage position of libSystem in the libjava
shared libraries on darwin. Will regression test next on x86_64-apple-darwin10.
