It is wrong, GCC 4.5.0 has been released already, so no new symbols should
be added to GCC_4.5.0 symver.
IMNSHO this isn't a regression fix, so you should just apply it to the
trunk, and introduce them as GCC_4.6.0 version.  Also, there is no need
to have two chunks for the same symver in the *.ver file, just put the
3 resp. 2 symbols before the preceeding closing brace, together with the
%ifdef/%else/%endif.
