>Description:

The preprocessor gives a strange error message
a.c:3:13: macro "foo" passed 2 arguments, but takes just 1
3 is the line number, but I don't know what 13 is.

>How-To-Repeat:

$ cat a.c
#define foo(x) bar

int foo(0, 0);
$ gcc -S a.c
a.c:3:13: macro "foo" passed 2 arguments, but takes just 1
