Nerius,

That's great.  I'm glad I was able to give you a starting point.

In C-mode, "C-h k DEL" tells me that DEL calls c-electric-backspace,
which in turn calls the function bound to c-backspace-function.

For me, c-backspace-function is bound to
backward-delete-char-untabify, which will convert a tab into a series
of spaces.

Maybe

    (setq c-backspace-function 'backward-delete-char)

is what you're looking for.
