Originally the problem was detected during an attempt to build FB3 on some recent Debian where a compiler requires int declaration before main. FB5+ has this fixed (8dee88fe931e44f3b3708c488aaeecfaabafdcd5) but it would be better to explicitly stop configure.ac processing if compilation fails because the problem may appear again for some different reason in the future.
