thanks for the fix; I have tried coccinelle 0.2.0 and it works fine.
Using the coccinelle/OCaml regexp seems to be way faster than just using
"identifier SPAM;" and filtering it later on in python. For my script on
a Wine C file it's the difference between finishing in 12 minutes or
killing the spatch process after 90+ minutes of burned CPU time (though
the python variant was timed with coccinelle 0.2.0-rc1).
bye
