That's the plan - however, no one has yet worked on it, cf. 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41209 -- To the bugs an 
incomplete patch is installed.
I am not aware of anyone working on it thus it probably will take quite 
some time until it will be supported. (But one never knows.)

Regarding the support for older versions: I think one needs to use 
conditional compilation to avoid problems with GCC 4.5/4.6. GCC defines 
with cpp |__GNUC_MINOR__| which cna be used to distinguish different GCC 
versions.
