I think you're twice off-by-one here,

: $ cvs -R ann -rRELENG_6_BP param.h | grep '#define.*__FreeBSD_version'
: 
: Annotations for param.h
: ***************
: 1.244        (sam      11-Jul-05): #define __FreeBSD_version 600032     /* Master, propagated to newvers */

but it still doesn't answer my question.  Why you've choosen
this __FreeBSD_version and not RELENG_6_BP (i.e., 600032).
I don't mind it, just want to understand the formulae.  :-)

Can you elaborate on what you mean here?  I don't understand.
Thanks.
