Petition p5p?

It seems you can't get an IV no matter what you do

SV*
bob()
    PREINIT:
        SV* temp;
//~         unsigned int uncle = 42;
        unsigned long long  uncle = 42;
    CODE:
//~         temp = newSVuv( 42 );
        temp = newSVuv( uncle );
        SvIOK_only_UV( temp );
        warn("we got em %p SvIOK_UV(%b)SvUVX(%u)", temp, SvIOK_UV(temp
+), SvUVX(temp) );
        RETVAL = temp;
    OUTPUT:
        RETVAL
