Hi Kai,

I have been looking into getting rid of those pesky linking issues - static
linking libgcc_s / libstdc++ although I've yet to find a decent solution. If
you've found anything related please let me know.

I would recommend that you put the libraries in the LLVM_LIBS variable via the
configure.ac script. In there you can check the existing and/or add heuristics
so that the libraries are added when necessary.

Thanks,
