Re: BSD detection

There is this piece of code in headers.h:

#ifdef __WXMAC_OSX__
#define __WXMAC__ 1
#define __WXOSX__ 1
#define __BSD__ 1
#endif
#endif

That code was a bad idea anyway, I’m deleting it.  Any Mac code should only use WXMAC_OSX, not WXMAC or WXOSX, and we should stop using BSD.

#if (defined(__unix__) || defined(unix)) && !defined(USG)
#include <sys/param.h>
#endif

Will that definitely cause BSD to be defined on Mac?
