Thanks for the report. Coccinelle is not actually trying to parse the #if
0 code. If you want it to do that, you should give the argument
-noif0_passing. But it is applying the lexer to it, and thus giving the
error message. As a short term fix, perhaps you could just try the -c++
option? I'll try to get rid of the error message.
