Problems with cgo translation. #1081
Description
by Bailey.D.R:
1. What is a short input program that triggers the error?
Here are two files making a package 'bug' The first, bug.h:
typedef int MyBool;
And the second, bug.go:
package bug.go
/*
* #include "bug.h"
*
*/
type Bool MyBool
Funnily, when the go file is changed to:
package bug.go
// #include "bug.h"
type Bool MyBool
the file compiles fine.
2. What is the full compiler output?

3. What version of the compiler are you using? (Run it with the -V flag.)
I'm running the version of cgo in the same build as "6g version 6080 release
release.2010-08-25".
