Hi,

I ran spatch --parse-c on the following code:

#define something 0,

int main() {
    return 0;
}

This code compiles fine according to the C standard, however the output of
spatch is:

init_defs_builtins: /usr/local/lib/coccinelle/standard.h

PARSING: test.c
ERROR-RECOV: found sync end of #define, line 1
parsing pass2: try again
ERROR-RECOV: found sync end of #define, line 1
parse error
 = File "test.c", line 1, column 20, charpos = 20
  around = '',
  whole content = #define something 0,
badcount: 0
BAD:!!!!! #define something 0,
-----------------------------------------------------------------------
maybe 10 most problematic tokens
-----------------------------------------------------------------------
something: present in 1 parsing errors
example:

       #define something 0,

-----------------------------------------------------------------------

Is this a known limitation? If not, is there a way to solve this issue?

Lucian
