* harbour/config/w32/bcc32.cf
* cleanup
+ harbour/config/w32/xcc.cf
+ added XCC support
* harbour/contrib/btree/hb_btree.c
* use hb_vmAtInit()/hb_vmAtExit() instead of INIT/EXIT functions defined
from C code
* harbour/contrib/libct/tab.c
* casting
* harbour/contrib/odbc/odbc.c
! removed #include <malloc.h> - it should not be used with new C
compilers
I think that we should replace this library with hbodbc from xHarbour.
* harbour/contrib/ole/ole2.c
* updated for XCC
* harbour/include/hbdefs.h
* include stdint.h if available
* harbour/source/compiler/complex.c
! fixed yet another stupid mistake in WITHOBJECT token
* harbour/include/hbpcode.h
* harbour/include/hbxvm.h
* harbour/source/compiler/genc.c
* harbour/source/compiler/gencc.c
* harbour/source/compiler/hbdead.c
* harbour/source/compiler/hbfix.c
* harbour/source/compiler/hblbl.c
* harbour/source/compiler/hbpcode.c
* harbour/source/compiler/hbstripl.c
* harbour/source/vm/hvm.c
+ added HB_P_SWAP <n> PCODE
* harbour/include/hbcompdf.h
* harbour/include/hbexpra.c
* harbour/include/hbexprb.c
* harbour/include/hbexprc.c
* harbour/include/hbexprop.h
! fixed GPF during compilation of @:var, @:&var, @o:&var
+ added support for @o:&var and @:var, @:&var inside WITH OBJECT
statement
* changed PCODE generated of ++,--,+=,-=,...
Now left side expression is evaluated _ONLY_ once and when object
messages are used it's guarantied that exactly the same object
variable will be used. It also fixes some problems which exists
in Clipper. This optimization is enabled by -kh flag (by default)
and can be disabled with -kc.
% optimize ald macros in ++,--,+=,-=,... operations
* add automatically "_" prefix when macro message is used in assignment
context, f.e.:
s:="osCode"
o:=errorNew()
? o:&s
o:&s := 100
? ++o:&s
? o:&s *= 5
* harbour/include/hblang.ch
- removed #xtranslate - this file is included by C code and some C
compiler do not like unknown directives
* harbour/utils/hbtest/rt_math.prg
+ added test code for <op>assign and (pre/post)(inc/dec)rementation,
macro messages and WITH OBJECT
* harbour/source/compiler/harbour.c
* harbour/source/rdd/dbf1.c
* harbour/source/rtl/errorapi.c
* harbour/source/rtl/hbgtcore.c
* harbour/source/rtl/gtdos/gtdos.c
* harbour/source/rtl/gtos2/gtos2.c
* harbour/source/rtl/gtpca/gtpca.c
* harbour/source/rtl/gtsln/gtsln.c
* harbour/source/rtl/gtstd/gtstd.c
* harbour/source/rtl/gtwin/gtwin.c
* casting and warning cleanup
* harbour/utils/Makefile
+ added $(HB_UTILS)
- harbour/utils/hbpp/hbpp.h
+ harbour/utils/hbpp/hbppdef.h
* harbour/utils/hbpp/hbpp.c
* harbour/utils/hbpp/hbppcomp.c
* harbour/utils/hbpp/hbppcore.c
* harbour/utils/hbpp/hbpplib.c
* harbour/utils/hbpp/hbpptbl.c
* harbour/utils/hbpp/pragma.c
* renamed hbpp.h to hbppdef.h to avoid possible conflict with hbpp.h
in include directory
* casting and warning cleanup
