OK, I'm not very eager to commit this change, because it will break C code
like:
if (x<y) ...
But if you have the source code, you can easily try it out and we can see
how useful it is. Here is a patch against the latest version (0.2.5-rc1):

If this turns out to be good enough to do some things, I can try to figure
out how to make this depend on some command-line option.
For your code, you will also want to make a file cpp.h containing:
#define RETVAL(x) x
And to run Coccinelle with the option -macro_file cpp.h
