================
Comment at: clang/lib/Headers/stdarg.h:21
+
+#ifdef __STDARG_H
 
----------------
Maybe the following is a little more readable?

```
#ifndef __STDARG_H

#ifndef __GNUC_VA_LIST
#define __GNUC_VA_LIST 1
typedef __builtin_va_list __gnuc_va_list;
#endif

#ifdef __need___va_list
#undef __need___va_list
#else
#define __STDARG_H
[...]
```
