Ok, that's the uncontroversial part.  Patch 4 has a whitespace error,
and patch 5 lost an #endif, so I'll resend them anyway.  I wonder how
the latter didn't surface on my home machine...  But there's another
failure I get on my work machine (with my original patchset with the
above errors corrected):

gcc -I../../src -g -O2 -g -Wall -O2 -Wall -Wl,-E -Wl,-rpath -Wl,/usr/lib/lxc  -o lxc-attach lxc_attach.o liblxc.so

liblxc.so: undefined reference to `lxc_sync_fini'

Have you got an idea what may be wrong here?  I'll continue
investigation after lunch.
