I'm not sure what you mean here.  If all programs are required to use
sfn's, what would be the point of implementing lfn's?
Also, having 'transparant' to the programmer like this would only work
for compilers that we can modify to make do so - in other words, no
Borland, no M$, etc.  Admittedly, I wouldn't touch their compilers
anyways, but someone else might.  What happens then?
