>> Here is a patch for the beos port (All regression tests are OK).
>> xlog.c : special case for beos to avoid 'link' which does not work yet >> beos/sem.c : implementation of new sem_ctl call (GETPID) and a new >sem_op >> flag (IPCNOWAIT) >> dynloader/beos.c : add a verification of symbol validity (seem that the >> loader sometime return OK with an invalid symbol) >> postmaster.c : add beos forking support for the new checkpoint process >> postgres.c : remove beos special case for getrusage >> beos.h : Correction of a bas definition of AF_UNIX, misc defnitions >> >> >> thanks >> >> >> cyril Cyril VELTER
