I downloaded free digital mars compiler 8.40c command line version and  
wondering if someone has
experience with using it with windbg ?
It's strange but with current windbg 6.3 version i can debug program but  
cannot show any local
variables or watch (new debug symbols version?).

I try to make simple hello.c like online help suggested with command line:

dmc -g hello.c

Debug with Windbg is OK but still I cannot inspect any variables
becouse of this error:

*************************************************************************

Another problem  with local variables is

0:000> dv
Unable to enumerate locals, Win32 error 50
Private symbols (symbols.pri) are required for locals.
Type ".hh dbgerr005" for details.

I know that it's not strictly related to Digital Mars but any help is  
really appreciated as
windbg is the only free debugger available for digital mars as i know.
Maybe old version of windbg is working better with Digital Mars  ?
Where can i find any info about working with windbg and Digital Mars ? Any  
other free symbolic
debuggers for Digital Mars (console version is ok)?

Short answer: Don't use Windbg. Purchase the CD and use the IDE's debugger.

Another option you might look into, because it's free as in software but 
not as in beer, is hacking the GNU libbfd (part of GDB) to understand 
COFF/OMF files (actually, it most likely does since I wrote some of the 
code waaaay back in a previous lifetime to support SCO Unix and Xenix.) 
You might need to do a recompile or two... and you might have to update 
the name mangling scheme, if it's not supported already.

I would try to extract internal codeview into PDB if it is possible.

The Symantec/Zortech/DMC IDE does show its age a little, but it's still 
a pretty decent IDE. I've been hacking at a DMC toolchain plug-in for 
Eclipse with some success (but not as much as I'd like with managed 
build projects.)

OTOH, if you're willing to work with GDB (Cygwin), you could make that 
work for you. Extracting codeview data into a PDB file may or may not 
work. If you do manage to come up with something, post it here too. I'd 
be somewhat interested.
