	* include/rw/_config-gcc.h [gcc >= 4.3 && __GXX_EXPERIMENTAL_CXX0X__]
	(_RWSTD_NO_VARIADIC_TEMPLATES, _RWSTD_NO_RVALUE_REFERENCES): Undefined
	to make it possible to use C++ 0x library extensions even in builds
	configured w/o C++ 0x extensions enabled in the compiler.
	(_RWSTD_EXT_CXX_0X): #defined in response to either of the -std=c++0x
	or -std=gnu++0x options.
