defconfig strangeness

HI !

doing a series of static code analysis on 2.6.34-rcX each of them with
defconfig (x86 32bit) - the strangeness is that even though the config
file is the same for rc3...5 the number of files actually compiled
is very different. (linux-2.6 git tree)

2.6.34-rc5 1695
2.6.34-rc4 3404
2.6.34-rc3 5109

I diffed the .configs - rc4/rc5 only shows

3,4c3,4
< # Linux kernel version: 2.6.34-rc4
< # Thu Apr 22 11:37:43 2010
---
> # Linux kernel version: 2.6.34-rc5
> # Thu Apr 22 10:44:02 2010

why then this large difference in files being compiled ?

any hint apprecieated.

thx!
