Indeed, this is one problem of using a too-old version of DejaGnu, i.e. 
predating the patch

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.

which is included in the documented minimum version (1.4.4).

http://gcc.gnu.org/ml/gcc/2003-05/msg01670.html
http://gcc.gnu.org/ml/gcc-patches/2004-11/msg00825.html

(The latter of these was followed by a long discussion on the binutils / 
gdb-patches / newlib lists of problems with this patch in particular 
cases, but 1.4.4 is still the minimum version and there is no longer a 
separate dejagnu copy in the src repository.)
