Loss on time issue is fixed (that was a bad bug: it was reading past an array end in the scoring routine). Also I found and fixed a problem in the book learning code. I'm still testing, but if all goes well version 11.2 should be out soon with these fixes.

I've ported some pawn race evaluation code that was in version 10.4 into the 11.0 sources (see this chess forum post for some discussion of a position that shows the need for this). It's still not working as well as I'd like but it's better than nothing.

I also have made a few changes to enable compilation under MacOS (on Intel hardware). Plus a few more Linux compliation fixes.

Recently there's an issue with losses on time when playing on a chess server (using the 64-bit Windows version). I'm investigating. This is currently holding up release of a new version.

So of course after releasing 11.0 I found a few problems. I had the 64-bit version crash a couple of times online and have tracked this down to some issues maintaining the PV list. There were also some reported problems compiling the source under Linux. So there is a patched version out now (11.1) with these and a couple other things fixed.
