           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2

 */# 2 "<built-in>" 2 3

gcc creates:


/*

 * Linux kernel version: 2.6.30
 * Sun Jun 14 11:37:11 2009
 */


Notice the missing newline before #2.
gcc doesn't output #2 at all.
However even if I manually add a newline, ld still rejects it.
I think no #2 should be output, to be compatible with gcc.

ld:arch/x86/kernel/acpi/realmode/wakeup.lds:6: ignoring invalid character `#'
in expression


Input file:
/*
 * wakeup.ld
 *
 * Linker script for the real-mode wakeup code
 */
#undef i386
#include "wakeup.h"
