Yes. Replace line 11 of configure from
  use_non_posix=
to
  use_non_posix="-DUSE_NON_POSIX"

Yes, it opens the input file with the O_DIRECT flag.

This is expected behavior. "remaining time" is not the time remaining to 
end the current run, but to rescue all the data in the rescue domain.

http://www.gnu.org/software/ddrescue/manual/ddrescue_manual.html#Algorithm

The 'remaining time' is calculated using the average rate of the last 30 
seconds and does not take into account that some parts may be excluded 
from the rescue (for example with '--no-trim'), or that some areas may 
be unrecoverable. Therefore it may be very imprecise, may vary widely 
during the rescue, and may show a non-zero value at the end of the rescue.
