> Indeed, for a while, the Go compiler was written in this special dialect of C, and so building Go required building a C compiler (!) that could compile this custom dialect of C, and using that to compile the Go compiler [2].

I don't think that's true. The build process used GCC to compile the Go and C compilers. The Plan-9-derived C compiler was used for compiling those parts of the runtime that were written in C back then and were supposed to follow the conventions of Go program code.

As you can tell from Inferno (or even Plan 9 from userspace), GCC can compile the Plan 9 C dialect, given the right options.
