As I said before <http://gcc.gnu.org/ml/gcc/2003-05/msg01670.html>, the 
system headers provided by GCC should be included by the testsuite harness 
with -isystem, please fix the bug there instead.  The tests are correct; 
it is correct to include <limits.h> in strict ANSI mode and not worry 
about its internals.  The problems was tracked to DejaGnu in the previous 
thread; and indeed it is fixed in DejaGnu 1.4.4 (documented in 
install.texi as the minimum required version), probably by

2002-11-12  Hans-Peter Nilsson  <hp@bitrange.com>

        * lib/libgloss.exp (newlib_include_flags): Use -isystem, not -I.
        (libio_include_flags, g++_include_flags, libstdc++_include_flags,
        winsup_include_flags): Ditto.
