* BeOS R3 compatibility. Be changed the property_info structure between

* R3 and R4 and these functions ensure that BPropertyInfo is backward
|

|
* compatible. However, between R3 and R4, Be changed the Intel executable

|
* format so R4 was not backward compatible with R3.
|

|
|
*
|

|
|
* Because OpenBeOS is only targetting Intel platform compatibility at this
|
||
|
|
* time, there is no need for R3 compatibility in OpenBeOS. By default

* these members will be turned off with the R3_COMPATIBLE define.
