AFAIU, it means that coccinelle made an incorrect replacement.

Yes, it's not a silver bullet (yet). And, of course, I'm not a heavily
experienced user.

I fixed both of these in revision 109332.


Btw, can't we have in Emacs a feature that would allow such
refactoring?  The replacements don't seem too complex to me.  Adding
this to Emacs will both allow getting rid of an external tool, and be
a valuable addition to Emacs abilities.  WDYT?

IIUC real refactoring of C should imply preprocessing and full
syntactic analysis, so, I'm thinking about GCC plugin.

Nevertheless, I suppose that it should be possible to build
simple refactoring engine on top of cc-mode, and such an engine
may provide basic features like intelligent renaming of identifiers
or tweaking function arguments.
