gcc 2.97 "fixincludes" breaks wnn/commonhd.h

Recent CVS gcc 2.97 on my Linux system decides it needs to
"fixinclude" wnn/commonhd.h.
Unfortunately, wnn/commonhd.h contains this:
#include "wnnerror.h"
When an application (such as xemacs) does
#include <wnn/commonhd.h>
gcc finds its "fixed" version of commonhd.h in a gcc-specific
directory. Unfortunately, there is no wnnerror.h to be found in the
same directory, so compilation ends with an error.
Here is a patch to xemacs, which has the unfortunate consequence of
disabling wnn when compiling with gcc-2.97, but it's better than
failing to compile.
