We can make cconv work while preserving the malformed bindings, but when
the compiler prints the warnings, there's a good chance that the
malformed binding that gets printed will not look like the binding as it
appears in the source, since cconv might transform the VALUE part.
Therefore I think it's preferable to use byte-compile-log-warning in
cconv.
