Bug#433572: asm/byteorder.h broken for gcc -ansi

["Daniel F. Smith" <dfsmith@almaden.ibm.com>]

Package: linux-libc-dev
Version: 2.6.21-6
Severity: normal

I have some software that compiles with the -ansi flag and includes
<asm/byteorder.h>.  This was fine under 2.6.18, but now...

~$ echo >test.c "#include <asm/byteorder.h>"
~$ gcc -c -Wall -ansi test.c 
In file included from /usr/include/asm/byteorder.h:7,
                 from test.c:1:

(Without -ansi, we get the expected result.)
~$ gcc -c -Wall test.c
