I don't think our current gcc defines bsd4_4, I'm certain it shouldn't. :-)
There's a well defined way to find out what version of the OS you're running
under.
#ifdef _HAVE_PARAM_H
#include <sys/param.h>
#endif
#if defined(BSD) && (BSD >= datecode)
...
#endif
This gives us much finer grained control.
The other change (__FreeBSD__=2) is absolutely positively correct.
