Thank you very much, Bump. It's clear to me. And also, I 'v read the mail send from Martin (http://lists.gnu.org/archive/html/gnugo-devel/2009-01/msg00006.html). Here I explains a bit more. At this time, the modified engines' source codes are not distributed with the binary entirely, I just provided the two modified .c files of each version with the GNU GO engine binary, and placed a 'readme.txt' file in the engine's directory that said that the modified files are here and the full source code can be downloaded from the GNU Go's homepage. Acroding to the GPL license, this seem's not enough. From now on, I'm going to provide GNU GO engine full source code download seperately on the release homepage, and explicitly add a link to the source code download page both in the 'readme.txt' and the GUI shell program beginning from the next release. Till now, all of my release of the GNU GO engine and the GUI are electronical (download from web site), if someday I need to release it by other meidia such as CD or DVD, I'm surely will provide the full source code of the engine.
Now, the entire source codes (from 3.0 to 3.6) of the engines modified by me are here: http://guohe.tiaoa.net/download/gnugosource30to36.zip Any question, please ask me, thank you!

If you made modifications to the GNU Go engine you have to distribute the source to the GNU Go engine. Your GUI that communicates with GNU Go through GTP is a separate program and you do not have to distribute source for it. Daniel Bump
