No, the precedent is to name the NEW ones __foostatfs13(), etc.  The 
signal stuff was an anomaly -- the intent was to use the libc major 
version that the new calls correspond to.

If we go all the way and supply statvfs, then we don't need to bother 
versioning the old call at all.  Just let it continue to exist, and 
truncate the values that would overflow at 2TB.  Make the old call 
dependent on COMPAT_16.

If you're going to bother implementing statvfs (something defined by a 
standard), then use the types that the standard says.  Using fixed-size 
types is nice, but if it means that you technically do not comply with 
a standard, then I think it's foolish to be stubborn about it.

Agree... I think we should implement the standard.
