* include/hbsetup.ch
! Minor fix in comments.
* contrib/xhb/hbcompat.ch
+ Added hb_rddInfo() translation for xhb apps.
* common.mak
* include/hbextern.ch
* source/rtl/Makefile
+ source/rtl/natmsgu.c
* source/rtl/natmsg.c
+ Added Harbour internal version of undocument Clipper
Nat*() (and friends) calls. These are always available
in core.
Harbour __natIsAffirm() = Clipper IsAffirm()
Harbour __natIsNegative() = Clipper IsNegative()
Harbour __natMsg() = Clipper NationMsg()
Harbour __natSortVer() = Clipper _NatSortVer()
Harbour __natMsgVer() = Clipper _NatMsgVer()
* utils/hbtest/rt_misc.prg
* source/rtl/dircmd.prg
* source/rtl/getsys.prg
* source/rtl/tgetlist.prg
* source/rtl/tlabel.prg
* source/rtl/treport.prg
! Now using Harbour internal __NAT*() functions
instead of C5.x undocumented calls, so Harbour
will now compile with HB_C52_UNDOC turned off.
