XP/2003 compatability fix

The attached patch fixes the bug that on XP fio fails with:

"The procedure entry point vsprintf_s could not be located in the
dynamic link library msvcrt.dll".

Only Vista and newer have the 'secure' functions, so we need to use
vsprintf to maintain compatibility with XP.
