Hello,
I try file_descriptor::seek() for a big file over 4GB on Win32,
but the result was not correct.
file_descriptor.cpp(185)
...
LONG lDistanceToMoveHigh =
           off < 0xffffffff ?
               static_cast<LONG>(off >> 32) :
               0;
I think that lDistanceToMoveHigh always becomes 0.
The condition above should be "off > 0xffffffff".
Yeah, this is definitely wrong. It should just be

  LONG lDistanceToMoveHigh = static_cast<LONG>(off >> 32);

It's hard to test features that require really huge files.

Thanks for pointing this out.
