With gcc 4.7 prerelease, gcc (GCC) 4.7.0 20120123 (Red Hat 4.7.0-0.9) as found
in Fedora Rawhide, sdt.h doesn't compile with g++ -std=c++0x

Other -std settings work fine.
Error look like:

[...]
I think this is a g++ bug since sdt.h contains:
# define _SDT_S(x) #x
Or is there a reason that doesn't work with c++0x?
