Somehow today the main branch seems to work (yesterday I got lots of
warnings and the kernel compilation broke...), so I could compile a kernel
with the latest CVS stuff. 

Now, I want to compile the utilities. Is it really necessary to copy the
utils to the kernel directory? I tried it with the below patch against
util/Makefile and 'make KERNELDIR=/path/to/my/kernel', but it breaks here: 

----------8<----------
ln -sf
/home/robert/embedded/ptxdist-0.1.1/build/linux-2.4.18-rthal5-jffs2/fs/jffs2/compr.c
compr.c
cc
-I/home/robert/embedded/ptxdist-0.1.1/build/linux-2.4.18-rthal5-jffs2/include
-O2 -Wall -Dprintk=printf -DKERN_NOTICE= -c -o compr.o compr.c
compr.c: In function `jffs2_decompress':
compr.c:135: warning: implicit declaration of function `printf'
compr.c:135: `KERN_WARNING' undeclared (first use in this function)
compr.c:135: (Each undeclared identifier is reported only once
compr.c:135: for each function it appears in.)
compr.c:135: parse error before string constant
make: *** [compr.o] Error 1 
----------8<----------

... which comes because in compr.c there is no #include <stdio.h> in case
of non-kernel code. The whole thing with -Dprintk=printf looks a little bit
like a hack, so is there a better way to compile the utilities?
