I continue to be fascinated by the idea of making a small smbd really
work (and so ease embedded vendors of Samba 3.x), so I got it down to
CFLAGS='-DMAX_DEBUG_LEVEL=1 -D__location__=__FILE__ -DSAMBA_SMALLER -O2 -flto -fwhole-program' LDFLAGS="-O2 -flto -fwhole-program " ./configure --bundled-libraries=talloc,tdb,pytdb,ldb,pyldb,tevent,pytevent --with-static-modules='!FORCED' --with-shared-modules='!FORCED' --nonshared-binary=smbtorture,smbd/smbd --with-system-mitkrb5 --without-ad-dc --without-ads --disable-python --without-ldap && ./buildtools/bin/waf --targets=smbd/smbd
