The Binary Compatibility package provides a set of libraries compatible with the SunOS 4.x libraries. Therefore, even if the interface or behavior of a routine has changed in the Solaris 8 release, user applications should not be affected when the Binary Compatibility Package is used.
Library routines that deal with the /etc/xtab file will not work correctly with the Binary Compatibility Package..
The order of locales in the string returned by setlocale() differs between the SunOS 4.x and Solaris 8 releases. This string is normally used by a subsequent call to setlocale(), and the order should not matter. Applications that rely on a specific order of locales may not be binary compatible.
