If you have done a compilation in the tree, it may have touched some of
the header files.  The way the kernel Makefiles take care of header
dependencies is that if a.h includes b.h, and b.h is newer than a.h, it
will touch a.h.

I usually keep separate trees and only compile in one of them.  I use
dirdiff to keep track of the differences between the trees.  Dirdiff is a
tool I wrote for seeing the differences between directory trees.  It can
handle up to 5 directory trees.  It's a tcl/tk script and it's available
at ftp://ftp.linuxcare.com.au/pub/ppclinux/dirdiff.
