* harbour/bin/hb-func.sh
* changed the exit code for .hrb file compilation by xhbcmp
* harbour/include/hbcomp.h
* harbour/source/compiler/gencc.c
* harbour/source/compiler/hblbl.c
* removed some variables which are not necessary in Harbour
* harbour/source/compiler/hbfix.c
+ added unconditional and conditional jump joining optimization
* harbour/source/vm/classes.c
* indenting and some minor modifications
* harbour/source/rdd/dbfcdx/dbfcdx1.c
! clear the logical key position buffer for pending relations
or hot record buffer updating
* harbour/source/rdd/dbffpt/dbffpt1.c
* harbour/source/vm/hvm.c
* casting
* harbour/source/vm/macro.c
* xharbour/include/hbvmpub.h
* removed HB_FS_ALLOCATED
* xharbour/source/vm/dynsym.c
* changed the code for hb_symbolNew() to avoid possible memory leak
alerts and keep the list of all dynamic symbols accessible.
It also reduced a little bit the memory fragmentation and total
size of memory allocated for dynamic symbols.
