Interesting.
I was assuming that Clang tends to understand "-lstdc++" as a special argument
that says "link against C++ standard library", not "link against
libstdc++.{a,so}".
For instance,
clang a.cc -lstdc++ -stdlib=libc++
will effectively replace "-lstdc++" with "-lc++", and
clang++ a.cc -stdlib=libc++ -static-libstdc++
will link against libc++ statically. In that sense, it makes sense to assume
that "-static-libstdc++" will bind to "-lstdc++" argument.
Apparently, it's not what GCC does :( Do you think we should keep being
compatible here?
