LLVM from the trunk from Oct 1, llvm-gcc-4.2's trunk from today, built with GCC
4.3.1 on an AMD64 bit linux. When building the source

int main(int, char*[])
{
}

with llvm-g++ test.cxx

I see 44 lines of output:
/build/axel/local/libexec/gcc/x86_64-unknown-linux-gnu/4.2.1/cc1plus: Symbol
`__gxx_personality_v0' causes overflow in R_X86_64_PC32 relocation

The binary still works despite the message. Some more info on the build:

What causes the message, is it a problem with the build of llvm or with a part
of llvm itself? Could the message be flagged as 'warning:' or 'info:'?
