[Cocci] Transformations for implementations of functions without explicit return type

[SF Markus Elfring]

Hello,

Does the current software "Coccinelle" support to transform implementations of
functions where a return type was not explicitly specified for it in a source file?

I think so, but perhaps not in the released version.

Would you like to try out if a function like "my_free" could be adjusted
after the reuse of your recent (unpublished) updates?

That is a pity.

Now it seems that a function like "my_free" could only be adjusted after
a patch will be applied from my bug report.

How do you think about the possibility to transform more such
implementation details from a Kernighan/Ritchie coding style to a
current C standard approach?

A manual software update is generally also possible. It would be nice if
more dedicated tools can help in a corresponding automatic conversion,
wouldn't it?
