Index: frysk-core/frysk/proc/ChangeLog
2006-01-07  Andrew Cagney  <cagney@redhat.com>

        * LinuxProc.java (getStat): Make package visible.
        (stat): Make private.
        * LinuxHost.java (ProcChanges.update): Use LinuxProc.getStat, not
        LinuxProc.stat.

was using LinuxProc.stat before it had been initialized; LinuxProc.getStat
ensures that that can't happen.
