Hi,

if I copy a compiled kernel tree to another location and run
make again in the new directory, a few files always get rebuilt.
These files only are rebuilt if the tree is a copy of another
tree and they are rebuilt only once.
Any ideas why this is the case?

arch=x86_64, make=3.80, filesystem=reiserfs

Log follows:
compiler@switch:/storage> cd linux-2.6.16/
compiler@switch:/storage/linux-2.6.16> make
CHK include/linux/version.h
