Arasan 11.0 is out now. I made a couple more scoring bug fixes and changes and a few code cleanups to reduce compile warnings on Linux.

A few more recent fixes:
- UCI crash fixed.
- Minor fix to "show thinking" display on Winboard.
- Fix to Queen vs. 2 Rook material scoring.
- Search fix (correct bounds on re-search).
Haven't been able to reproduce the tablebase move problem.

The new engine version (11.0) hasn't changed much lately. I put in some rook mobility fixes after the last ACCA tournament. The latest issues I am working on are:
- A crash in UCI analysis mode (stack corruption, it looks like).
- An issue found in looking over a game from the OpenWar tournament: Arasan had a won position from tablebases, but it played a wrong move and lost (this was 10.4, but I am afraid the same issue may be in 11.0).
- A few other positions where the engine may be misbehaving.
So I'm getting close to a releasable version, but I want to get to the bottom of some of these issues first.
