Nonsense. Just putting GCC source code in to the BSD repository wouldn't magically spread the requirement that the entire project become GPL any more than keeping a copy on my hard drive requires I give the FSF the complete contents of my /home directory. What matters is the dependency/linkage. The GCC 'runtime library exception' firewalls all 'target code' from the GPLv3, and even allows proprietary preprocessors, linkers and assemblers (but nothing that would involve modifying GCC to split what it does in to more granular stages)
