Whether that is true depends on what the Program does. The binary you make by compiling using GCC is the output of GCC, therefore it is not covered by the GPL unless you want it to be. This is deliberate by RMS. Any statically linked GNU or Linux library functions that might be copied into your binary are ok because the libraries are not covered by the GPL but by another different license. Again, this is deliberate by RMS, because he wanted GCC to be useful even for people doing proprietry software. I suppose this is marginally relevant to CCC because some of the people here (shock! horror!) actually write computer chess programs, and might be considering using GCC or other GPLed compilers to do so. But maybe we should move the discussion to e-mail now, and just summarise to CCC when we reach a conclusion.
