What did you do?

Tried to build this cgo sample from https://golang.org/cmd/cgo/

package main

// typedef int (*intFunc) ();
//
// int
// bridge_int_func(intFunc f)
// {
//		return f();
// }
//
// int fortytwo()
// {
//	    return 42;
// }
import "C"
import "fmt"

func main() {
	f := C.intFunc(C.fortytwo)
	fmt.Println(int(C.bridge_int_func(f)))
	// Output: 42
}

What did you expect to see?

This should built without errors. Builds fine in 1.15.6

What did you see instead?

command-line-arguments

cgo: exec C:\Program: exec: "C:\Program": file does not exist

I reverted to 1.15.6 and it builds fine without errors.
