It didn't, but there are two others:
/vol/gcc/src/hg/trunk/local/libgo/runtime/go-setenv.c: In function 'setenv_c':
/vol/gcc/src/hg/trunk/local/libgo/runtime/go-setenv.c:44:3: error: implicit
declaration of function 'setenv' [-Werror=implicit-function-declaration]
One needs to check for putenv vs. setenv and handle that in
go-setenv.c. I've hacked around the issue for the moment to at least
let bootstrap succeed.
Besides, there are many errors compiling cgo_unix.go and cgo_linux.go:

All those errors are caused by the fact that <netdb.h> only exposes
struct addrinfo and the AI_* and EAI_* defines if _NO_XOPEN4 &&
_NO_XOPEN5, but we need _XOPEN_SOURCE=500 for other reasons. So I've
again chosen to hardcode them in socket_irix.go.
With this patch (and the setenv/putenv hack), I've been able to
successfully build libgo.so on IRIX 6.5.
