Give better error message for named pointer receiver types #1680
Description
The following program errors out with a message "invalid receiver type MyPtr".
Because the C typedefs were done in someone else's header, I hadn't realized that btype
was a pointer type. Something more helpful might be "MyPtr: named pointer types
may not be receivers"
1. What is a short input program that triggers the error?
package mine
// typedef int atype;
// typedef void* btype;
import "C"
type MyInt C.atype
type MyPtr C.btype
func (m MyInt) DoSomething() {
}
func (m MyPtr) DoSomethingElse() {
}

2. What is the full compiler output?
# make (with a standard cgo makefile)
CGOPKGPATH= cgo -- cgo.go
touch _obj/_cgo_run
6g -o _go_.6 _obj/cgo.cgo1.go _obj/_cgo_gotypes.go
cgo.go:12[_obj/cgo.cgo1.go:15]: invalid receiver type MyPtr
make: *** [_go_.6] Error 1
3. What version of the compiler are you using? (Run it with the -V flag.)
6g version release.2011-03-07.1 7666+ (but really I think it's cgo)
