Need strsafe.h

HI,
microsoft just released a new header file that replaces some of the older c string functions, they help to prevent the possibility of buffer overruns and other such nuisances, anyhow to get the new header i needed to download the core SDK update, however it only runs on newer versions of windows, not including the win98 that i run, so i was hoping that someone somewhere had a copy of this header, or if they have smoking fast internet and downloaded the SDK themselves, if they could be so kind as to send me a copy of the header....thanks.
