The problem is that the API changed (subtly): CL_FLEVEL got increased.

The exported function is not check_flevel, but rather cl_retflevel, 
which just returns CL_FLEVEL.

I think this is the wrong workaround.
The correct fix is to bump the minimal version requirement of 
cl_retflevel to 0.98.5~rc1, which is the upstream version in which 
CL_FLEVEL changed the last time.

We'll have to do that in the future every time CL_FLEVEL is increased.

It is important to note that c-icap-modules also uses cl_retflevel, even 
though it doesn't use CL_FLEVEL directly. Thus it can't have a runtime 
test failing with older libclamav.

Best regards,
Andreas
