It operates on memo files only (.dbv) without tables (.dbf)
To create .DBV file use:
dbCreate( cFile, {}, "DBFBLOB" )
* harbour/source/rdd/dbcmd.c
* do not report error when empty structure table is passed to DBCREATE()
CL5.3 allow to create even DBF files without any fields and because
I can imagine some valid code which use it as a feature then I also
allow it in DBF RDD.
Authors of RDDs which do not allow to create tables without fields
should add to their low level RDD code necessary RT error.

If someone has time then it will be good to also add:
hb_xvmDivByInt(), hb_xvmModulusInt(), hb_xvmPlusInt(), hb_xvmMinusInt()
* harbour/source/vm/itemapi.c
* use simple memcpy() in hb_itemSwap() - it's save in current HVM
It could become unsafe if we add reference tracing or sth like

* declare BYTE * passed to hb_codeblockNew() as const
* harbour/include/hbpcode.h
! fixed the PCODE numbers in PCODE description, 122 was repeated for
two different PCODEs: HB_P_ONE and HB_P_MACROLIST
* harbour/source/compiler/genc.c
! fixed hb_p_functionshort pcode size returned by genc function
! fixed double value presented in verbose genc mode for HB_P_PUSHDOUBLE
! fixed number of cases presented in verbose genc mode for HB_P_SWITCH
* harbour/source/compiler/hbdead.c
+ added support for dead code elimination in functions which uses
SWITCH ...; CASE ...; ...; END syntax
* harbour/source/compiler/harbour.c
* harbour/source/compiler/hbfix.c
! fixed optimization for HB_P_PUSHLOCALNEAR and HB_P_POPLOCALNEAR.
It was a long existing bug not reported so far because 0, 1 and 2
PCODEs uses only one BYTE and bad PCODE tracing in hbfix.c didn't
caused bad side effects as long as number of locals in function
was smaller then 768. Now for functions HB_P_PUSHLOCAL and
HB_P_POPLOCAL is used and later changed to NEAR version in hbfix.c
if possible.
* harbour/source/compiler/hbfix.c
* join sequential jumps to optimize constructions like:
while ...
...
if ...
exit
endif
enddo
* harbour/source/compiler/hbdead.c
* remove HB_P_END PCODE also at the and of function if is repeated
just before, f.e. in code like (source/rtl/color53.prg):
Function RADGRDEFCO( cColor )
if isdefcolor()
Return applydefau( cColor, "W/N", "W/N", "W+/N")
Else
Return applydefau( cColor, 3, 1, 4)
endif
Return nil
Now such redundant constructions like above are fully stripped by
compiler anyhow if someone has time and think is important then can
clean also this .prg code.
* harbour/include/Makefile
* harbour/include/hbcomp.h
+ harbour/include/hbxvm.h
* harbour/source/compiler/Makefile
* harbour/source/compiler/cmdcheck.c
* harbour/source/compiler/genc.c
+ harbour/source/compiler/gencc.c
+ harbour/source/compiler/hblbl.c
* harbour/source/compiler/hbpcode.c
* harbour/source/vm/hvm.c
+ added support for generating real C code not PCODE in .c files.
Now with -gc3 Harbour will generate .c files with real .c code
which is later compiled to real machine code.
I left PCODE only for code block definitions though it's also
possible to have even code block compiled to machine code but
we will have to add a flag to codeblock structure which will
be checked at runtime and proper method of execution in EVAL
will be chosen. If you think it's worth of afford then I can
add it too in some spare time.
The final binaries are noticable longer then the one which has
only PCODE but they are faster. The speed improvement depends
on type of operations. The pure Clipper code which does not
execute any external time consuming C functions compiled with
-gc3 is from 10% to 50% faster.
The side effect of generating pure machine code is also harder
recompilation but it does not mean that is impossible. If sth
can be executed by some machines (virtual or hardware) then it
can always be decompiled by definition.
This modification opens door for farther optimization, f.e. when
we will have fully working strong type support then we can add
using native .c types.
In fact this module is PCODE to .c translater not part of compiler
and can be used as separate module to translate generated PCODE,
f.e. .hrb files.
Maybe in the future we will change the compiler to generate meta
code not directly PCODE and it will be possible to make optimizations
on this meta code which will depend on selected output type:
VHM PCODE, C code, .NET code, etc. but at this moment adding support
for .c compilation directly into compiler will make the compiler code
too much complicated for me - IMHO it's better to invest time into
clear separation to FRONT_END->REAL_COMPILER->BACK_END
Please make test with your code. I rebuild whole Harbour code with
-gc3 set in HB_FLAGS in harbour/config/rules.cf and all seems to
work correctly. hbtest returns exactly the same results.
I also made tests with my programs and they work correctly but
I had to define actions for all PCODEs and it's possible that made
some typos in some of them which are very seldom used so your tests
will be very important.
* harbour/source/lang/Makefile
- harbour/source/lang/msgen.c
* harbour/source/rtl/langapi.c
* moved EN lang definitions to core lang code so we always have at
least one lang module defined at sartup.
Modified after common group agreement - no one was against,
thanks to all for answers.

* harbour/source/rtl/hbgtcore.c
* respect pure REQUEST HB_GT_NUL as user GT choice if only GTNUL
is linked
* harbour/source/rtl/errorint.c
! fixed GPF when no lang module is register - I'll wait a while for
other people opinion and if no one will give good reason against
then I'll make EN language definition default part of langapi.c
what will resolve the problem of valid error description when no
language module is linked.

programs.
+ harbour/source/rtl/gtwvt/Makefile
+ harbour/source/rtl/gtwvt/gtwvt.c
+ harbour/source/rtl/gtwvt/gtwvt.h
+ added new GT driver GTWVT - the core of this driver it's Peter Ress
work in xHarbour. In Harbour GTWVT contains only pure GT code without
local to GTWVT xHarbour extensions and GTWVT contrib libraries.
This extensions can be added but later but I want to keep them
separated from the core GTWVT code and add them as upper level GT
which can inherit from GTWVT. Just like I've implemented CTWIN.
Please update non GNU make files and test this GT in Windows.
The programs which want to use GTWVT should be compiled as standard
Windows GUI programs. GTWVT replaces window console code.
if you add to your code:
proc GTSYS()
request HB_GT_WIN
request HB_GT_WVT
return
then the final binaries will be linked with both GT drivers and you
can switch between them using //gt[:]<name> switch. F.e.:
./my_prog //gtwin
or
./my_prog //gtwvt
this feature works in all platforms.
People who works in shell environment (*nixes, MSYS, DJGPP) and use
hb* scripts does not have to use GTSYS() in source code but can simply
use -gt<name> switch in hblnk and hbmk.
* harbour/source/rtl/gtxwc/gtxwc.c
* some minor cleanups and code formatting
* harbour/source/vm/Makefile
+ harbour/source/vm/mainstd/Makefile
* moved mainstd.c to separate mainstd library for MinGW32 build.
Unfortunately MinGW always link main() function if it locate
it in libraries and ignores WinMain() what effectively makes
impossible to create Windows GUI programs if we have main() in
VM library. People who are using MinGW and wants to create only
pure console programs should now include mainstd library to linked
library list.
* harbour/source/vm/cmdarg.c
