    The only bit I don't understand is this one in

+#define LIBGCC_SPEC "%{shared: -lgcc_pic} %{!shared: -lgcc}"

ah, very cool, somebody read it completely :)

this makes gcc link libgcc_pic for shared libs and libgcc for static libs. this is needed for amd64, because shared pic code can't get certain fixups for non-pic libgcc. the libs still stay static.
