[clamav-users] Can't compile under gcc 7.2.0

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 is more 
strict.

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

Am I the only one?

Frans.
