Oh dear you miss a lot of points!
Zahak is not released under GPLv3, but MIT...
I have no issues people test Zahak, and I am also happy about people having interest in them. That is why I release binaries.
I honestly don't pay much attention to your results, all I care is you not calling it Zahak 9.0, but Zahak 9.0-Compiled By ... or Zahak-9.0-modified or whatever, just to avoid confusion.
I expect you to appologize for your very rude statement here, I give away something for free, I don't need to be greatful.
As I said, I have no issue you running Zahak. I don't even have the right to complain however you test it. I have released it under MIT after all.
BUT I do have all the right to forbid you to call it Zahak 9.0, call it whatever you like. Is this too much to ask? Call it Zahak 9.0-derivative, Zahak 9.0-compiled-by-..., Zahak-9.0-like or whatever. BUT THIS IS NOT ZAHAK 9.0, its source code/or Makefile is for sure modified or it cannot compile for Android
