Samba4 does not compile on Ubuntu i686

[Zahari Zahariev]

  Hello Jelmer & list,

  After your last commits this morning (http://pastebin.com/0J1qKQM7) 
all of my Ubuntu machines started to produce 'make' error -- 
http://pastebin.com/0ZQgb0Da. However I do not see that on the official 
buildfarm Ubuntu machines (they are all x86_64). Also I do not have this 
issue on my Debian Lenny machine.

Can you look closer into this issue? Is someone else having this problem?

Thanks!
