Bug#522095: kernel build fails, because zlib.h is missing

["W. Martin Borgert" <debacle@debian.org>]

Package: linux-source-2.6.29
Version: 2.6.29-1

I'm using make-kpkg to build the kernel, but zlib.h
(dependency on zlib1g-dev? or the kernels zlib.h?) is missing:

$ make-kpkg --initrd --revision=2:my.1.0 --rootcmd fakeroot --uc --us  
kernel_image
...
