# Build a version of emacs that is not linked to the X11 libraries:
CFLAGS="$SLKCFLAGS" \
LDFLAGS=-s \
./configure \

   --prefix=/usr \
   --with-x=no \
   --with-pop || failconfig

# Break the hard link 'emacs' - we only want the version number at this stage
# anyway. This wouldn't be a problem if we were building the X version next:
( cd /usr/bin
  mv -f emacs-$VERSION emacs-$VERSION-no-x11 
  rm -f emacs )

# Build the full X11 emacs:
CFLAGS="$SLKCFLAGS" \
LDFLAGS=-s \

    --with-x11 \
    --with-x-toolkit \
