[Buildroot] Known working versions ?

[Koenraad lelong <buildroot@de-brouwerij.be>]

Hi,
I'm very new at system-building, so excuse me if I'm asking "old" 
questions. In that case, please redirect me to the answers.
A few days ago I did an svn checkout, and with "make menuconfig" I made 
a .config file. When I "make" it, I get compile-errors (in busybox, or 
elsewhere). This morning I did an svn update, with more or less the same 
  results.
Since I think of svn as a system where you don't always have good 
results, I would like to know a revision-number that is known to be 
good. And I also would like to have a .config-file known to be good. 
That way I could start from something that should be good, so if I have 
problems, they have to come from my host-machine (a Suse 10.1 system 
b.t.w.).
Ah, I would like to make an ix86-system with a (recent) 2.16-kernel.
I hope I'm not unreasonable when I ask these, thank you for _any_ help.
P.S. just to test I downloaded the recommended gumstix-buildroot and 
that seems to compile fine.
Regards,
Koenraad Lelong.
