GCC 4.7 has incomplete C++11 support, so you're going to have problems
using C++11 anyway. Later releases only issue a warning for invalid
suffixes on string literals:
udl.cc:5:19: warning: invalid suffix on literal; C++11 requires a
space between literal and string macro [-Wliteral-suffix]
const char* s = ""X;
^
Asking for a new option to disable user-defined literals isn't going
to help you anyway, because no new option is going to be added to GCC
4.7.2
And the option isn't needed with current releases.
