Hi,
here is updated patch addressing the code duplication.  With __builtin_ctzl

Not an objection to this patch as there are several existing cases of this issue, but I think scattering GCC_VERSION conditionals across the source tree (a few places also have __GNUC__ conditionals) is bad style.

There are also a number of comparisons GCC_VERSION >= 3400 which, while working in practice (only 3.4 is filtered out), are wrong.
