- Nothing was supposed to have changed, as far as I know. Without seeing
- your code and a detailed description of how it fails, it's impossible to
- tell whether there's something in your code that's dependent on details
- of the IPC implementation that aren't nailed down by the SVID or some
- other spec, or something in SunOS 4.1.2 that's broken.
