I have preprocessed my main.cpp, which is the only cpp file listed in 
the original error:

In file included from http_server_signals.hpp:12:0,
                 from http_server.hpp:21,
                 from http_service_traits.hpp:15,
                 from main.cpp:14:
/usr/include/sys/wait.h:155:52: error: ‘siginfo_t’ has not been declared
 extern int waitid (idtype_t __idtype, __id_t __id, siginfo_t *__infop,

Here is the preprocessed output for the http_server_signals.hpp file:

If I am reading this correctly, the siginfo_t definition is available 
when preprocessed.

Is there anything obvious that I might be missing?

Thanks,
