+Use --without-all if you want to build a small executable with the minimal

+X support, use --without-all --with-x-toolkit=no.  For the smallest possible

 Use --with-wide-int to implement Emacs values with the type 'long long',
 even on hosts where a narrower type would do.  With this option, on a
 typical 32-bit host, Emacs integers have 62 bits instead of 30.
