It's being reported that some systems (as Ubuntu 13.04) already have struct tcp_repair_opt definition in their system headers. | sk-tcp.c:25:8: error: redefinition of struct tcp_repair_opt | sk-tcp.c:31:2: error: redeclaration of enumerator TCP_NO_QUEUE So add a facility for compile time testing for reported entities to be present on a system. For this we generate include/config.h where all tested entries will lay and source code need to include it only in places where really needed.
