C++ and Qt 4.4. We also use Doxygen for API documentation, and Git for version control.

Great! That seems to be the way to go.

Success!

To get the man command use it on my Ubuntu I had to rename it to xboard.6, gzip it, and move it to /usr/share/man/man6/xboard.6.gz

Installing the man page should normally have been handled by autoconf/automake....

I think these are supported on MACOSX as well.

I never use profile-generated optimization with GCC, simply because it doesn't work for me.

That's strange. I experimented with it with Toga and it seemed to work. But I did not do
any serious testing.

I assume you did profile? -fprofile-use seems to missing from you command line.

Yes, it has come a long way from it's stable Fruit roots. It appears to be connected to the threading code, as reducing the number of threads increases the time between failure. I will try less aggressive optimizations to see where I get. Have you run many longer time control games with many thread...

Actually I see that you are now proposing a convention more akin to Shredder fen. This has as an advantage that the offset of a rook in the table of random numbers would not change if an outer rook became an inner rook. But it would not be compatible with the way PG currently encodes Chess960 positi...

I included the Chess960 specification in

Please have a look if there are any remaining ambiguities.

You clearly said that you find a GPLed program worse than a copyrighted program. Since virtually every program is copyrighted this means that you find a GPLed program worse than any other kind of program included closed source ones.

So I think I interpreted you correctly.

You have a word of 4 letters chosen from a-h (or empty). So 4x8=32. This is like the current situation where you represent a word of 4 bits by 4x1 keys. But i already said I agree to 16. But you said you would want to reduce it further since every file indicator can take only 5 values (apart from kq...

I would not try to look for clever schemes to minimize the number of extra random numbers required. This is not worth the effort. The most important thing is that the hash key should be as simple as possible to compute. The main feature of PG books is and should be that they are trivial to implement...
