Hacking linux-kernel 2.6.17
***************************

Linux kernel 2.6 has decided to work around gcc weirdness
and therefore it conflicts with ncc's nognu macros.  You'll need to
edit some files in include/linux. The following patch is to demonstrate
the required changes (if you have gcc3. for another gcc edit the
apropriate file(s)). It's best to apply the patch *manually*.

Then edit the root Makefile to use ncc

	HOSTCC = ncc -ncgcc -ncfabs -ncld -ncspp
	CC = $(CROSS_COMPILE)ncc -ncspp -ncfabs -ncgcc -ncld -ncquiet
	AR = $(CROSS_COMPILE)nccar -ncquiet
	LD = $(CROSS_COMPILE)nccld -ncquiet

Also edit the file `scripts/Makefile.build` and search for the
line 'cmd_modversions =' and modify it in such a way:

#########################################################################
 		rm -f $(@D)/.tmp_$(@F) $(@D)/.tmp_$(@F:.o=.ver);	\
 	else								\
 		mv -f $(@D)/.tmp_$(@F) $@;				\
+		mv -f $(@D)/.tmp_$(@F).nccout $@.nccout;		\
 	fi;
 endif
#########################################################################

Then compile your kernel. If all goes well, the file vmlinux.nccout
should appear.  Then do

	nccnav vmlinux.nccout

to hack it.  If you are building into another object directory (like
`make O=/tmp/kernobj`), then it is much better to invoke the nccnav
viewer from the root of the source tree.  As

	nccnav /tmp/kernobj/vmlinux.nccout

so that pathnames are relative -- and small.
