I get no answers, so if nobody has this problem, I go the tedious way of 
compiling a bug report.

Using the tar on the current OpenSuSE Tumbleweed, I get:

--------------------------------------------------------------------
Compiling on the same and also different machines with gcc 4.8.3 works 
correctly. Looking at the messages it seems to me that gcc 7.2.0, 7.2.1 
and 7.3.0 are more strict.

Also, this behavior was also in rc1/2 of 0.99.3.

-----------------
Using the git with checkout 0.99.3, it does compile more but then the 
next error came:

-----------------------------------------------------------
with master, I get the same errors as above.

Sofar, clamav is not usable anymore on (at least) with gcc 7.2.0, 7.2.1 
and 7.3.0

Am I the only one?

Regards,
Frans.
