[boost] SVG plots, utility, Spirit and C4127 in debug

I've run a tiny demo program using Jake Voytko's GSoC SVG plot code.

In debug (but NOT in release) I get lots of warnings like:

C:\Program Files\Microsoft Visual Studio 8\VC\include\xutility(2938) : warning C4172: returning address of local variable or
temporary

        I:\boost_1_34_1\boost/spirit/utility/impl/chset/range_run.ipp(70) : see reference to function template instantiation 'const
_Ty &std::max<CharT>(const _Ty &,const _Ty &)' being compiled
        with
        [
            _Ty=unsigned long,
            CharT=unsigned long
        ]

Can I safely disable these worrying sounding level 1 warnings?

Is this a bug or a (compiler) feature?

Paul
