It doesn't make too much sense to speak of an official ABI for Go in
general.  gccgo uses the usual C ABI on any given system.  The way that
gccgo represents Go types in C terms is documented at:
http://golang.org/doc/gccgo_install.html#C_Interoperability .  Though,
as noted, some of the implementations are still subject to change, so in
that sense there is no final ABI.

The 6g and gccgo compilers are never going to interoperate.  6g uses a
different approach to compilation, a different object file format, a
different calling convention, etc., all in the name of fast compilation
rather than fast execution.

Yes, will do.
