I hadn't taken GCC 4.6 into account when making the patch for GCC 4.7. 

I suggest making the check in MathExtra.h into:
#if !COMPILER(MSVC) && !COMPILER(RVCT) && !OS(SOLARIS)
using std::isfinite;
#if !COMPILER_SUPPORTS(CXX_ISINF_ISNAN)
using std::isinf;
using std::isnan;
#endif
using std::signbit;
#endif

And setting WTF_COMPILER_SUPPORTS_CXX_ISINF_ISNAN for compilers that has isinf and isnan in the global namespace.
