I have a djgpp cross-compiler (i586-pc-msdosdjgpp-gcc) setup on GNU/Linux after following the instructions on the website and have confirmed it functions correctly. However i'm not sure how i can use it to compile djgpp software, such as emacs, for DOS. The v2gnu/ emacs READMEs as well as msdos/INSTALL in the emacs source tree only explain how to do it on a DOS system with djgpp.
