Hello libtool list,
We recently came across the following bug on Fedora:
https://bugzilla.redhat.com/show_bug.cgi?id=2043517
While investigating it, we came to the conclusion that libtool seems to
wrongly deduplicate the following postdeps:
postdeps="-lstdc++ -lm -lgcc_s -lc -lgcc_s"
That leads us to the following change in principle:
diff --git a/build-aux/ltmain.in b/build-aux/ltmain.in
index e4efc925..5e8014e8 100644
--- a/build-aux/ltmain.in
+++ b/build-aux/ltmain.in

In other words, and if we are not wrong, the more the time passes, the more
this case grows.
Then the question is, wouldn't it make sense to actually have
"opt_duplicate_compiler_generated_deps=:" as the default behavior, and be
done with it ?
