[cfe-dev] linking and stripping compared to GCC 4.4

Different hard drives. They are the same file, I swear.

I ran gcc 4.4 on Linux and clang on MacOS X indeed.

Fair enough. I did not take the time to install gcc 4.4 on my MacOS X machine indeed. Nevertheless, this begs the question: is clang++ hampered by MacOS X binary format to such an extent that the -s stripping option has no effect whatsoever? Whereas g++ 4.4 on Linux is able with the same option to significantly reduce the binary size thanks to the superior ELF 64-bit format? Or could clang++ do better as a linker driver on MacOS X here?
