modification history
--------------------
01i,24jun11,y_t  req WIND00236547: improve nfs ls performance.
01h,07may10,lxj  change fsId and inode from ULONG to UINT for NFS protocol
01g,29apr10,pad  Moved extern C statement after include statements.
01f,01sep06,mwv  update the include paths
01e,01dec05,dlk  Use __INCnfs2dLibh rather than __INCnfsdLibh to protect
                 against multiple inclusion (SPR #114404).
01d,08aug03,bmk  added extern declaration for group_export (SPR #4220)
01c,21apr94,jmm  more cleanup of prototypes; added NFSD_ARGUMENT
01b,20apr94,jmm  added new prototypes
01a,31mar94,jmm  written.
