* harbour/include/hbsetup.ch
* enable HB_COMPAT_FLAGSHIP by default
I hope it will not be a problem - if it does then I can disable it
but in *nixes for a long time FlagShip was the only one Clipper
alternative and some of its functions are quite often used in
Clipper/FoxPro programs ported to *nixes so I'd want to keep it
enabled at least when HB_OS_LINUX/HB_OS_UNIX is defined.
* harbour/include/hbvm.h
+ added missing extern in hb_vmAtInit() and hb_vmAtExit() declarations
* harbour/include/hbvmpub.h
* formatting
* harbour/source/rdd/dbcmd.c
! fixed the problem with fieldput(<n>,nil) at phantom recrod reported
by Victor
* do not use C level HB_ITEM
* harbour/source/rdd/dbf1.c
* harbour/source/rdd/dbfcdx/dbfcdx1.c
* harbour/source/rdd/dbfntx/dbfntx1.c
! fixed possible GPF when "/an/existing/path/" was used as file name.
No in DOS in such case it will casue RT error that file:
/an/existing/path/.<ext>
cannot be created (like in Clipper) but in other systems (f.e. Linux)
which allow to use such file names it will work without any problems.
* harbour/source/rdd/dbffpt/dbffpt1.c
* do not use C level HB_ITEM
* harbour/source/rtl/Makefile
+ harbour/source/rtl/strpeek.c
+ added STRPEEK and STRPOKE FS functions covered by HB_COMPAT_FLAGSHIP
macro
* harbour/source/rtl/philes.c
! fixed GPF when unshareing string item buffer with embedded 0 by using
hb_itemUnShare()
* harbour/include/hbapiitm.h
* harbour/source/vm/itemapi.c
+ added hb_itemUnShare() - /* un-share given string item */
and hb_itemClone() - /* clone the given item */
