Yes, thought so. >> (A) Red Hat, the "/usr/lib/libunwind.la" should not have ' -lc -lgcc' >> as a dependency, those are implicit and should never be in a >> ".la", except maybe when building the compiler/linker itself? > > Maybe.

That is part of what I hoped to get an answer to, is it ever right to list "-lc" and "-lgcc" in the ".la" file 'dependency_libs=...' ? I would guess you are not supposed to do that, except maybe when building the compiler/linker itself, libraries "internal" to the compiler. Maybe the real bug is that there is a "libunwind.la", should not have been installed? Hmm.... I nevert tried removing it, what "$CC -v" using icc would list then. But might even require a reinstall of icc to change the output from "$CC -v". And if it is ok to have "-lc" and "-lgcc" in 'dependency_libs', should libtool pick them up an insert them in the middle of a link line? Maybe it should exclude all libraries "$CC -v" listed when reading 'dependency_libs'?
