 Thanks for answering.

Thanks for pointing out where places dumper in.
Yes, E2K, when Linux is installed, is a common Posix platform.
No important messages around, only in/out directory and compiling. But i
can send this btw, then will be working with the machine again.
Could you say, how to compile emacs with debugging information? I mean
proper building with scripts like this:
./autogen.sh
./configure --with-x-toolkit=no --with-xpm=no --with-jpeg=no --with-png=no
--with-gif=no --with-tiff=no
make
make install

And how do you advise debugging Elisp code?

And where to send the patches? To this mail?

Thanks for helping.
