I took a look at the gcc source - there's definitely no flag to disable
that warning, but #pragma GCC system_header will do the trick (recent
versions of libstdc++ use variadic templates with or without c++0x
support enabled). It won't work in C++ source files, just in headers;
adding #pragma GCC system_header will tell GCC to treat everything from
the pragma to the end of the file as a system header. Note that this
will disable a boatload of other warnings.
