Oh, it is my guilt! I've forget put all necessary files in the
package. Sorry, because it has taken your time.

The best way to avoid problems of such type is installing cygwin:

http://sources.redhat.com/cygwin/

(you can choose only necessary package, i.e. bison and flex.
They contains all needed files like bison.simple etc).

Well, I use 1.32 because it included in the distribution of Linux I
use. I've checked and all worked well under 1.34. But I will try
update my bison to 1.34 to avoid unnecessary problems in a future.

Hm...

The tale about our *.y and *.l files is that they are generated and no
one should modify they. May be it is ugly, but it is the only method I
can found:

We have common parts, they lay in lib/uvm. When we create grammar
files we glue 3 parts: parser1.ys + parser_cmn.ys + parser2.ys and get
parser.y. And the same with lexer.l. Thus, the true way is change *.ys
and *.ls and don't change *.y and *.l - they should be assembled in
the custom build step you will provide.

But I think you already know it.

Well, you, of course, can change these files (*.ys, *.ls) if there are
problems with build.

Really you shown good ability of resolving problems. Don't worry about
terms I've picked in a task. We are working with such agreement:

Anybody of us can make new task and can change task if I've assigned
it. Because our work is voluntary and I don't know about how much free
time you will have for working for this project all terms are
tentative. But we need to know these terms, so it is your right change
terms after I've assigned a task, and I will see when YOU plan finish
it. But it is bad practice change it at the end of this time interval,
so try plan/change tasks such way that you will be able finish it
according to your own plan.

You can change tasks when you are logged in on SourceForge through you
personal page (you may be know about it). When you will change a task
I will get a notification.

Also, the good practice is update percent of completion in assigned
tasks.

I invite you follow these rules. 


> I did n't get any problems with lexer file.

OK.

Hope hear you soon.
