and, alas, microsoft has made sp2 unavailable and xp next year is support EOL except for embedded. so SP1 users (like me) are out of luck unless they have already downloaded and burned a copy of SP2 and SP3. after EOL, updates will no longer be available from http://windowsupdate.microsoft.com, just like with windows 9x/me/2000.

Well, in general I agree.  We might should do same hack (for older
msvcrt versions) as we do for vscanf (as example).
