I didn't spot any others.

Yes.  Backporting

%inherit GCC_4.6.0 GCC_4.5.0
GCC_4.6.0 {
}
%inherit GCC_4.7.0 GCC_4.6.0
GCC_4.7.0 {
}

in libgcc-std.ver is easy.  (The latter isn't yet in trunk, it's added by 
<http://gcc.gnu.org/ml/gcc-patches/2011-04/msg02130.html>; whatever the 
first patch to go in trunk with GCC_4.7.0 symbol versions is needs to add 
it to libgcc-std.ver.)
