The syscall package varies by platform, and TCGETS, for instance, is defined for Linux- http://golang.org/src/pkg/syscall/types_linux.go http://golang.org/src/pkg/syscall/types_linux.go -but not for Darwin- http://golang.org/src/pkg/syscall/types_darwin.go http://golang.org/src/pkg/syscall/types_darwin.go So it seems somewhat Linux tied.
