Here I've got output:

/usr/lib/coccinelle/spatch: unknown option `-very_quiet'.
Usage: spatch -sp_file <SP> <infile> [-o <outfile>] [-iso_file <iso>] [options]
Options are:
[...]


I use ubuntu Lucid 10.04 as said in Documentation/coccinelle.txt.

$ LANG=C apt-cache policy coccinelle
[...]
  Installed: 0.2.0.deb-1ubuntu2
[...]


If I delete -very_quiet then It runs OK, but output is not ommited:

I think it is more usefull to use $M instead of $srctree to run simple
'make coccicheck'.
