Hmmm, the plot thickens... I'm using VS2005 which doesn't find it - 
although 'intrin.h' defines it like this:-

    __MACHINEIW64(unsigned char _BitScanReverse(unsigned long* Index, 
unsigned long Mask))

So I wonder if it was initially only available for 64-bit compilation, 
then later got ported to 32-bit??

Also, it's MSDN entry doesn't specify that any link lib is needed so 
I've been assuming it gets implemented as a macro (?)
