Right BCC version to use ?

Hello all,

I wonder which BCC I should use to build ELKS and my tools.

I see in the main README that two versions are available:
1- https://github.com/lkundrak/dev86 (original)
2- https://github.com/jbruchon/dev86 (copy)

I currently use the version 1 that is provided in my Gentoo distribution.

Could you explain why you instruct to use the copy (version 2) in that 
README ?

Regards,

Marc-F. Lucca-Daniau
