hb_compCodeBlockStop() looks like work in progress or is has
some old unused code - Ryszard, can you look at it?
* harbour/source/macro/macro.y
* removed hack for GCC and old Bison versions
* harbour/source/pp/ppcore.c
* removed unnecessary initialization to avoid BCC warnings
* harbour/source/pp/pptable.c

* harbour/source/rdd/dbfntx/dbfntx1.c
* synchronized with xHarbour - still dbcmd.c has to be synced yet
! fixed all known bugs
Alexander, please look at DBFNTX - I hope all is correct.
* harbour/source/vm/codebloc.c
* formatting
* harbour/source/vm/fm.c
+ added HB_PARANOID_MEM_CHECK to force reallocations in hb_xrealloc
and fill allocated and freed memory with HB_MEMFILER (0xff by default)
It's for debugging only.
* harbour/source/vm/hvm.c
! fixed hb_vmTopNumber() declaration for BCC
* use hb_gcCollectAll() at HVM exit instead of hb_gcReleaseAll() to
report allocated and not freed items - It could caused that some
programs begin to report memory leaks.
* harbour/source/vm/itemapi.c
* check for HB_IS_BADITEM inside hb_itemClear() when compiled with
HB_PARANOID_MEM_CHECK for debugging
* harbour/source/vm/memvars.c
* formatting
! fixed pItem initialization in hb_memvarDetachLocal()
BTW - is this really necessary? I copy it form hb_itemUnRef()
but in fact it cannot detect all possible item reference cycles
if they appear - can they appear?
