Yeah; this is why its so bloody silly Apple aren't distributing the headers
with the OS - the two can get out of sync :-/

There is a /usr/include/Availability.h file which includes,

#define __MAC_10_0      1000
#define __MAC_10_1      1010
#define __MAC_10_2      1020
#define __MAC_10_3      1030
#define __MAC_10_4      1040
#define __MAC_10_5      1050
#define __MAC_10_6      1060
#define __MAC_10_7      1070
#define __MAC_NA        9999   /* not available */


If you've got 10.6 headers installed; then I'd imagine the __MAC_10_7
contact would be undefined…  Perhaps a good enough handle to make a choice?

Cheers,
