+ * Header-shadowing guard (Linux only).
+ *
+ * glibc's <sys/signal.h> is literally one line: "#include <signal.h>".  Every
+ * module compiles with -I<...>/libthecore/include, so that bracket include
+ * resolves to *this* file instead of /usr/include/signal.h, and SIGPIPE,
+ * signal(), sigaction() and friends silently disappear.  libthecore's own
+ * stdafx.h includes <sys/signal.h>, so this bites signal.c immediately, and
+ * db/src/Main.cpp and libsql/Tellwait.cpp include <signal.h> directly.  (It
+ * does not happen on FreeBSD, where <signal.h> includes <sys/signal.h> and not
+ * the other way round, which is why the production build never hit this.)
+ *
+ * Pull the real header in via #include_next, which resumes the search after
+ * the directory this file was found in.  _SIGNAL_H is glibc's own guard, so
+ * when the system header already got in first this is a no-op.
