Ah, I see I got the Intel version check backwards, fixed (hopefully!)

I'm not convinced that _GLOBAL_USING is used consistently between Dinkumware
libraries (windows vs linux etc), so I'd rather not rely on _GLOBAL_USING at
all - hence my attempt to check the Intel version number.

I don't think it's possible to check for that as far as I know :-(
