Does it possible to modify DMD and publish it in that form. Of course with full
information about authors. Does it legal?

It depends.  If you ONLY modify the front-end (front-end files are
identified as being licensed under GPL [1]), then you can distribute the
modified front-end.

However, if you modify the back end, you cannot redistribute those
files.  You also cannot distribute a compiled version.

To be safe, it's probably best to just distribute any changes you make
as a patch.

[1] There's another license involved, but I forget what it's called.
