Hi,
I just wanted to mention a trivial patch I attached to the Ubuntu bug
for this. It has the drawbacks that Colin mentions above that its not
the standard semantics of _LARGEFILE64_SOURCE and _FILE_OFFSET_BITS=64
It does however fix the problem of the missing prototype and should
not be too bad (given that the functions are dynamically mapped anyway
on 64bit systems).
Cheers,
Michael
