For what it's worth, this breaks compatibility with gcc-4.4, but gcc-4.4 is using a really bad mangling here, and the ABI has moved on.  I don't know if later GCCs have updated their manglings — presumably they have — but given that '0x support is still preliminary in all these compilers (and will necessarily be so until the standard actually comes out), I am not worried about this incompatibility.  I'm willing to accept patches from distribution maintainers who feel very strongly about maintaining mangling compatibility with gcc-4.4.
