Hello,

We have just upgraded a server to Ubuntu 18.04, running kernel
4.15.0-142-generic. Compiling DAHDI 3.0.0 fails with the error below, and
3.1.0 gives the same error. The gcc compiler is version 7.5.0. Would anyone know what the solution is, or should we open a bug report? Thanks in advance for any help!
