version.h is generated by the build system for official builds of
FlightGear. To avoid complicating the life of regular developers,
especially on Windows, we set HAVE_VERSION_H if version.h is generated.
If that define is not set, we include this file instead, which provides
placeholder values instead.
#include <simgear/compiler.h>
#include <simgear/debug/logstream.hxx>
+#if defined( HAVE_VERSION_H ) && HAVE_VERSION_H
#include "version.h"
+#else
+# if !defined(SIMGEAR_VERSION)
+# define SIMGEAR_VERSION "development " __DATE__
+# endif
+#endif
