I'm just guessing here, but I think because of the dots it's returning
a string instead of a number which makes the >= comparison invalid. Is
there another gcc option that will give you a "dotless" version
number?
I would try something like:
%global gccver %(gcc -dumpversion | sed "s/\.//g")
%if %{gccver} >= 460
foo here
%endif
