cmd/cgo: some cgo messages mention C.unsignedchar but that is not a valid type

[bits01]

When using C.uchar in code and getting some compilation errors, the error message mentions C.unsignedchar but that doesn't seem the be a valid type.

package main

import "C"

import "fmt"

func main() {
    var c C.uchar = "5"
    //var c C.unsignedchar = 5

    fmt.Println(c)
}


% go run main.go
# command-line-arguments
./main.go:8: cannot use "5" (type string) as type C.unsignedchar in assignment

"5" is string literal not character literal. it should be:

package main

import "C"

import "fmt"

func main() {
    var c C.uchar = '5'
    //var c C.unsignedchar = 5

    fmt.Println(c)
}

Yes, I know that. The example is on purpose to show the error message. The bug is about the error message itself. Type C.unsignedchar doesn't exist, the error message should read "type C.uchar"

sorry misunderstanding.
