You have to apply this to the source code and then compile dosbox yourself. You can either look at the diff file in editor, open the file it mentions and change the lines accordingly or if you have a working built setup use the patch utility

How to compile the DIFF in DOSBOX??

How to open DOSBOX, to compile?

Apply it to the sources. There's enough info out to be found with google about that.

You don't compile the diff into dosbox. You apply the diff to the source code of dosbox and THEN you compile this source with a compiler. If you have no clue of what I'm writing, don't bother...

Thank you for the information. I have only one question, what would not climb on google, what programs? are necessary to edit the source code.

Now I have such a thing. I want to change the code of the finished DOSBOX. How to do this? And is it possible? Or to find back the old code and do again.

Wut?

source code is mostly text files. You really should get a beginners tutorial for programming. You are asking questions that show that you really need to learn first before asking here. We cannot hold your hand through everything and it seems we'd need to.
