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.

Presumably you can modify and distribute LDC (under the GPL terms if it is GPL. I forget)?

LDC = Front End + LLVM
