different from HB_OS_UNIX_COMPATIBLE, it may be possible that
it's not 100% the same as before, although their meaning was
the same.
HB_OS_UNIX_COMPATIBLE is still available for compatibility, but
it's now marked with HB_LEGACY_LEVEL2 and will be removed in next

! Using HB_CFLAGS/HB_PRGFLAGS to specify Makefile local
compiler settings instead of modifying HB_USER_*FLAGS.
This way the double defines are gone.
+ Included global.cf to all Makefiles which needs to modify
HB_CFLAGS/HB_PRGFLAGS. Probably we should move global.cf
inclusion to the top of all Makefiles as a convention.
Not terribly elegant, but solves a few problems and
more efficient.
% Changed ', -I$(d))' to ',-I$(d))' along the way. This avoids
wasting an extra space in command line.
; NOTE: It'd still be beneficial to find a way to get rid of
'descend' rule. It could make cmdlines cleaner/shorter
and whole build process simpler/faster. I didn't manage
so far.
* source/vm/Makefile
* Deleted 'HB_USER_CFLAGS := $(subst -DHB_MT_VM,,$(HB_USER_CFLAGS))'
(since it's no longer supported practice to modify user supplied flags)
I'm not sure if it's important enough to have. AFAIK there is no
reason users use HB_MT_VM define, it's not a public setting, so we
shouldn't go too much far in trying to protect against its presence.
If it's needed, we should add 'HB_CFLAGS += -DHB_ST_VM' and handle
HB_ST_VM as the reverse of HB_MT_VM inside the source.
* source/rdd/dbffpt/dbffpt1.c

! Including 'global.cf' directly to make HB_ARCHITECTURE/HB_COMPILER/HB_COMMERCE
variables work in case we're relying on autodetection.
; TODO: May need to do this for a few other cases where detection is relying
on some additional variables. Like HB_XBUILD, which needs to be
cleaned further, maybe autodetection added.
; NOTE: Above changes mean that from now on for basic build usage it's
enough to have the compiler in PATH and to issue a simple 'make'
or 'mingw32-make' (or whatever GNU Make is called in that environment),
and make process should just work. IOW, no need to go through
"starter" scripts in root (make_gnu.*).

* harbour/include/Makefile
+ harbour/include/hbsocket.ch
+ harbour/include/hbsocket.h
* harbour/source/rtl/Makefile
+ harbour/source/rtl/hbsocket.c
+ added new BSD socket functions: hb_socket*(). They should be quite
close to low level C socket interface with few modifications which
help to hide some platform differences. Unfortunately we do not use
autoconf so I had to arbitrary set which features are available
on some platforms. In practice it means that it reduces portability
to older OS-es, i.e. it should work with current Linux versions
but it will not without some modifications in macros used to control
supported features with older Linuxes using kernel 2.2 or 2.0.
The same can happen with other *nix ports like Darwin, SunOS, HP-UX
or with different versions of some Windows compilers. I also do not
know which functionality is available in OS2 GCC ports and I would
like to ask OS2 users to make tests and disable not working features.
We also need tests with HP-UX, Darwin and SunOS.
IP6 support is enabled only in *nixes. If Windows users are interested
in IP6 then please add support for it. Most of Windows compilers do
not support standard POSIX functions so I do not want to make it
myself using unknown for me API without testing.
In *nix builds PF_UNIX/PF_LOCAL sockets are also supported.
Support for other socket types can be easy added if someone is
interested in them.
The constant values used in hbsocket.ch are equal to original BSD
socket definitions. If it's necessary then it's possible to enable
their translation inside hbsocket.c code though I do not think we
will find such OS.
The list of hb_socket*() functions was designed to cover all existing
functionality in hbinet.c and socket.c. Most of functions supports
timeout parameter what effectively allows to hide direct select()
usage.
Please make test with real applications and report any problems
with hb_inet*() functions you will find.

Old function name still available for compatibility.
* contrib/hbwin/win_reg.prg
* contrib/hbwin/win_regc.c
! GETREGISTRY() fixed to return default only if the
registry entry doesn't exist. Previously it was
falling back to default even if the value existed but
was empty. In case of empty string, these weren't
possible to write from hbwin, but could exist in registry
when written by other tools.
! GETREGISTRY() fixed to return binary data as string
for REG_BINARY types. (previously it was returning
an unsigned int - essentially truncating everything
beyong the first 4 bytes).
! GETREGISTRY() fixed to swap words for REG_DWORD_BIG_ENDIAN
values to return correct unsigned integer results.
(not tested)
! GETREGISTRY() fixed to strip only the ending Chr( 0 )
from string values. This makes it possible to utilize
strings containing nul chars (obviously) and also to
parse REG_MULTI_SZ multistring values.
! GETREGISTRY() fixed to not RTE if WIN_REGQUERYVALUEEX()
returned non-null length and a non-string value.
I still have to understand how this was possible, but
I got a report that it happened on a system.
! WIN_REGQUERYVALUEEX() fixed to store NIL in 5th param,
if the registry entry doesn't exist.
! WIN_REGQUERYVALUEEX() fixed to store empty string when
registry value is zero length.

* include/Makefile
+ include/hbapinet.h
* source/rtl/hbinet.c
+ Moved some basic declarations to new API header,
mainly to export hb_select[Read|Write]*() functions.
We will also need such header in the future when
we implement C level socket/networking API. Current
solution is quite messy since the header has to
pull Windows headers which may not be friendly with
all usages/include order.
* source/rtl/hbinet.c
* HB_SOCKET_STRUCT renamed to HB_SOCKET.
+ Added PHB_SOCKET type.
+ Added hb_selectReadFD(), hb_selectWriteFD() which
are similar to hb_selectReadSocket() and
hb_selectWriteSocket() but expect raw FD plus explicit
timeout values.
These function names and solutions are tentative
to solve SSL integration with Harbour, and hopefully
in the future we will have a clean net API, the current
one is very messy.
* source/vm/itemapi.c
! hb_itemPutCPtr(), hb_itemPutCLPtr() fixed to put empty
string to item if szText is NULL and length is non-zero,

* harbour/source/rtl/idle.c
* harbour/source/rtl/filesys.c
+ implemented OS independent task switching system - it gives PTHREAD
compatible basic API so it can be used in HVM as alternative MT support
which does not use any OS threads. As long as Harbour does not call
any blocking OS function then it's possible to create and execute
simultaneously many threads though only one CPU is used and switched
between HVM threads. It gives similar scalability to xbase++ threads
and also similar behavior in item protection at .prg level.
Now it's possible to use HVM threads in any OS.
Of course it does not mean that Harbour adds in some magic way
thread support to OS-es which does not support threads like DOS.
It only means that HVM supports threads for .prg code just like
in native MT environment as long as some C code does not block
task switching or process execution will not be frozen by sth, i.e.
executing other process (__run()) in single process OS like DOS.
In some cases it can be interesting alternative even in OS which
have native thread support.
All tests/mttest*.prg programs and speedtst --thread=<n> --scale
are executed correctly with new task switching just like with
OS native MT support.
Compilation with task switching in hbvmmt library can be forced
by HB_TASK_THREAD macro which also disable native OS threads
support.
For task context switching two alternative methods are used:
1) getcontext()/makecontext()/swapcontext() (SUSv2, POSIX.1-2001)
which is preferable because does not need any additional
hacks but not all OS-es supports these functions.
It's enabled by default in Linux builds.
2) setjmp()/longjmp() (POSIX, ISO 9899 (C99)) otherwise.
These functions are supported by most of C compilers
but there is no function to set new stack in saved context
so it's necessary to introduce for each architecure/C compiler
peace of code which makes it. Macro HB_TASK_STACK_INIT() in
task.c makes it. I defined this macro for x86@32 in DJGPP
Linux GCC and OpenWatcom builds. I tested OpenWatcom builds only
in DOS and Linux but probably it works in all x86@32 builds.
If someone is interesting in adding support for some other
platforms which does not support ucontext.h and 1-st methods
then please define above macro for them.
Have a fun with new toy ;-)
* harbour/source/vm/Makefile
* enabled hbvmmt in DJGPP and OpenWatcom DOS builds. It works well.
Viktor if possible please add support for -mt switch in hbmk2
in all builds even if we do not compile hbvmmt by default so
it can be used with DJGPP and OW and any other builds for which
someone enable hbtask.c though OS does not support threads.

+ added direct support for pushing references to macro expressions.
It resolves the problem with Clipper compatibility (thanks to Alex
for information and example) in code like:
m->var := {0}
&("var[1]") += 10
and also many other things, f.e. now Harbour can cleanly compile
and execute this code:
proc main
local s
m->o := errorNew()
s:="o:tries"
? m->o:tries
? &s
? &(s+"+=2")
? m->o:tries
? &(s+":=3")
? m->o:tries
?
&s := 4
? m->o:tries
&s -= 2
? m->o:tries
&s++
? m->o:tries
?
s := "o"
m->o := 1
? &s
&s := &s + 4
? &s
? &s += 5
? --&s
?
s := "o[2]"
m->o := { 1, 2 }
? &s
&s := &s + 4
? &s
? &s += 5
? --&s

In the above case, usage wasn't consistent,
LONG and long were mixed.
