* [Bug preprocessor/20356] New: New #include_next behaviour breaks limits.h

If some /usr/include header uses
#include "limits.h"
instead of
#include <limits.h>
it gets error: #include nested too deeply.
There are 2 limits.h headers, /usr/lib/gcc/*/*/include/limits.h and
/usr/include/limits.h that try to include each other with #include_next,
guarded with the defines that protect multiple header inclusion for the other
one.
" instead of < causes /usr/include/limits.h to be included first
(normally is /usr/lib/gcc/*/*/include/limits.h first) and this does:
#if defined __GNUC__ && !defined _GCC_LIMITS_H_
/* `_GCC_LIMITS_H_' is what GCC's file defines. */
# include_next <limits.h>
In older GCC releases, this include_next would load the next limits.h in the
search path, which is /usr/lib/gcc/*/*/include/limits.h, but GCC4 includes
/usr/include/limits.h again (and does so until reaching the nesting limit).

Indeed. If I back out:
http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/libcpp/files.c.diff?r1=1.3&r2=1.4
http://gcc.gnu.org/cgi-bin/cvsweb.cgi/gcc/libcpp/files.c.diff?r1=1.1&r2=1.2
it works just fine.
