siginfo_t should be declared by <bits/siginfo.h> which is included
from <signal.h>

You probably have another file in your search paths called signal.h
which is being included instead of /usr/include/signal.h

Look through the output of preprocessing (use the -E option to g++)
and see what headers are being included, and if they are the right
ones.
