last known 4-.x-RELEASE where PicoBSD can be built

[Nikos Vassiliadis]

Hi,

I tried to build PicoBSD using sources from RELENG_4 on a
4.10-RELEASE-p5 system and it failed. I (think|know) it's working
again on RELENG_6, but I want to use 4.x branch. So, which
sources should I get to build it?

Thanks a lot in advance

Nikos
