Hi Julia.

Would it be possible for a semantic patch to scan for
function definitions where the types do not have
identifiers and update the definitions to match the
declarations?

For instance, given:

<some.h>
int foo(int);

<some.c>
int foo(int bar)
{
	return baz;
}

Could coccinelle output:

diff a/some.h b/some.h
[]
-int foo(int);
+int foo(int bar);
