+modification history
+--------------------
+01z,05jun12,pad  Moved inclusion of sys/stat.h into a non-POSIX PSE52
+		 conforming section. Did the same for the declaration of the
+		 DIRPLUS structure for the RTP environment (defect #310319).
+01y,24jun11,y_t  req WIND00236547: improve nfs ls performance.
+01x,14jan11,pad  Include base/b_ino_t.h instead of types/vxTypes.h (defect
+                 218143).
+01w,28apr10,pad  Moved extern C statement after include statements.
+01v,07may09,lyc  LP64 support
+01u,09aug07,pad  Used the new _Vx_BOOL type instead of _Bool (different size,
+                 defect 100623).
+01t,10may06,pcm  undid changes from version 01s
+01s,08may06,pcm  modified dirent and DIR structures
+01r,28feb06,pes  Remove parameter names in function prototypes (per POSIX).
+01q,13feb06,dcc  added POSIX naming compliance when in user space.
+01p,18jan06,mil  Updated for POSIX namespace conformance (P1).
+01o,17jan06,md   added readdir_r
+01n,01oct05,md   changed d_name to use _PARM_NAME_MAX
+01m,28jul05,act  add an "end of dir" flag to a DIR for FIOREADDIR ops
+01l,20jul05,jlk  added d_ino field to dirent struct for POSIX.
+01k,09apr04,dat  adding const to char ptrs
+01j,22sep92,rrr  added support for c++
+01i,04jul92,jcf  cleaned up.
+01h,26may92,rrr  the tree shuffle
+01g,04oct91,rrr  passed through the ansification filter
+		  -fixed #else and #endif
+		  -changed VOID to void
+		  -changed copyright notice
+01f,10jun91.del  added pragma for gnu960 alignment.
+01e,05oct90,dnw  added rewinddir() and closedir().
+01d,05oct90,shl  added ANSI function prototypes.
+                 made #endif ANSI style.
+                 added copyright notice.
+01c,07aug90,shl  added IMPORT type to function declarations.
+01b,25may90,dnw  moved NAME_MAX to limits.h
+		 added copyright
+01a,17apr90,kdl  written.
