* harbour/source/common/expropt2.c
* casting
* harbour/include/hbdate.h
+ added hb_dateJulianDOW() - retrieve day of week from Julian's date
* harbour/source/rtl/dates.c
* harbour/source/common/hbdate.c
* moved hb_dateDOW(), hb_dateDecStr() and hb_dateEncStr() to
hbdate.c - Ryszard I'd prefer to keep this function together
It will be much easier to update them.
+ added HB_STR_DATE_BASE for conversion to string - Clipper
compatibility though we are not 100% Clipper compatible in STOD()
because we will have to reduce functionality (supported date
range) to reach it. In Clipper STOD(DTOS()) is not revertible.
I decided to make it revertible in [x]Harbour for the whole supported
in string conversion range: 0000/01/01 : 9999/01/01
% optimized hb_dateEncode()
* some minor fixes for Clipper compatibility
* harbour/source/rtl/dateshb.c
* use faster and Clipper compatible hb_dateJulianDOW() instead of
hb_dateDOW()
* harbour/source/rdd/nulsys/Makefile
- harbour/source/rdd/nulsys/nulsys.prg
+ harbour/source/rdd/nulsys/nulsys.c
* replaced .prg code with #pragma begindump/enddump by native C code
rtl/symbol.prg have to be updated yet.
* harbour/source/rdd/dbf1.c
* harbour/source/rdd/dbffpt/dbffpt1.c
* synced with xHarbour
