+ added support for thread local memory allocators by using MSPACE
mechanism in DLALLOC.
It can be enabled by compiling Harbour with HB_FM_DLMT_ALLOC macro.
By default up to 16 (HB_MSPACE_COUNT macro) independent memory
allocators is dynamically created for new threads. When more threads
is used then allocators are shared between them and HVM tries to
balance used allocators to reduce number of threads using the
same allocator.
It should give noticeable scalability improvement in some OS-es
where default memory manages has pure MT performance.
Please try to compiler speedtst.prg with Harbour compiled with
and without HB_FM_DLMT_ALLOC and compare results in this test:
speedtst --thread=2 --scale
using real multiCPU machine.

checking MinGW version
* source/common/hbfopen.c
* Changed hb_fopen() to use fopen_s(), secure version of
fopen() for MSVS 2005 and upper.
* source/common/hbstr.c
+ Added hb_snprintf() Harbour wrapper for snprintf() which
terminates the buffer with a '\0' char for CRTLs that
need this (like MSVC).
MSVC _snprintf() doesn't do so.
* hb_snprintf() used _snprintf_s(), secure version of
_snprintf() for MSVS 2005 and upper.
; TOFIX: There is still one strcpy() marked as non-secure
in debug lib. Could someone please take a look
at it and replace it with hb_strncpy() or something
else secure? The code is cryptic and as someone
not using the debugger, I didn't dare to touch it,
and this is the only one such call left.
; TODO: Change all snprintf() calls to hb_snprintf().
When that happens, Harbour will no more use anything
depicted as "non-secure" by MSVS 2005/2008.
; NOTE: This function may need tweaking, pls review and
fix if/where needed.
* source/vm/dlmalloc.c
! Fixed MSVC C++ mode compile error. This fix also exists
as part of the next dlmalloc version (2.8.4b).

* contrib/hbdbgfx/dbgfx.prg
* Minor cleanup.
* contrib/hbdbgfx/dbgfxc.c
! Fixed GPF when non-string parameter passed to
hb_outdebug().
* harbour/source/vm/fm.c
+ harbour/source/vm/dlmalloc.c
+ added alternative memory manager written by Doug Lea
It can be activated by recompiling Harbour with HB_FM_DL_ALLOC macro.
Please make test on different platforms with different C compilers.
Linux users will not benefit from it because the default GLIBC MM
is derived from a version of code.
NOTE: the results may strongly depend on total memory allocation
and will be different then in simple memory tests.
