* harbour/bin/hb-func.sh
* support for detecting startup function in C++ mode
* harbour/include/hbapi.h
* some few #defines to translate some xHarbour functions names to Harbour
* harbour/include/hbxvm.h
* harbour/source/compiler/gencc.c
* harbour/source/vm/hvm.c
* harbour/source/vm/itemapi.c
* harbour/source/common/hbdate.c
+ added optimizations for add and div by integer value
* changed code generated for double values to avoid limitation in some
C compilers like MSC and possible differ conversion inside C RTL then
the one which uses Harbour RTL
* some minor optimizations, cleanups and code formating
* harbour/source/compiler/hbfix.c
* optimize usage of HB_P_NOT PCODE - remove repeated NOT operations
or revert conditional jumps if they are just after NOT.
* harbour/source/rdd/dbf1.c
* added support for NULL value set in memo fields by ACCESS
* harbour/source/rdd/dbfcdx/dbfcdx1.c
* fixed ordKeyPos() - for records out of scope
* harbour/source/rtl/padc.c
* harbour/source/rtl/padl.c
* harbour/source/rtl/padr.c
* harbour/source/rtl/substr.c
* some minor optimizations to avoid new string item creation when
it's not necessary
* harbour/source/vm/classes.c
* harbour/source/vm/extend.c
* minor code formatting and optimizations
