What are you trying to compile there? I don't really know what the exact cause of the error is, but googling shows it is maybe due to using of different versions of gcc.
If you give more info on what is causing this error and which distro are you using, maybe it will be more helpful.

Well that's what I doubt. I think this toolchain for arm uses gcc 3.x. So, it requires gcc 3.x more specifically 3.2.x installed on your FC. Just install gcc 3.2.x that is available for FC 5. IMO, that should work for you.

Hi,
Don't just download the newest tarballs and try to compile. They gave error always. Instead try to use a toolchain building tool like crosstool or so. They will download the matching tarball and then compile them.
