                                                    The recommended way
                                                    is not to substitute
                                                    directly in a make
                                                    rule, but use a
                                                    variable.

The best would be to get rid of the #ifdef NS_IMPL_GNUSTEP, and use the
default rule for temacs${EXEEXT}, passing the correct flags in the
existing variables, or add new ones if needed.  Given that not too many
people work/even have access to GNUStep, help getting that right would
be greatly appreciated.

Now looking at the log:

./configure --prefix=/usr --host=i686-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --program-suffix=-emacs-23 --infodir=/usr/share/info/emacs-23 --without-carbon --with-sound --with-x --without-toolkit-scroll-bars --with-gif --with-jpeg --with-png --with-rsvg --with-tiff --with-xpm --disable-font-backend --without-freetype --without-xft --without-libotf --without-m17n-flt --with-x-toolkit=gtk --without-hesiod --with-ns --disable-ns-self-contained --without-kerberos --without-kerberos5 --with-gpm --with-dbus --build=i686-pc-linux-gnu
configure: WARNING: Unrecognized options: --without-carbon, --disable-font-backend
^^^^^^^^^^^^^^^^^^
This warning is obvious...

--with-x --with-x-toolkit=gtk make no sense when using --with-ns
--with-gif --with-jpeg etc, are turned on by default, no need to bother with them. 

You can try to get around the byte compilation problem by first
configure --with-x, do a make to create the .elc files, and then
reconfigure --with-ns and try again.  It's a hack, but it might help
until someone finds a proper fix.
