There was a thread which discussed this very subject not so long ago.
Briefly though, DJGPP is a protected mode compiler which means that there is
quite a lot of code which is used to set things up in pmode. This is
unavoidable, but for larger programs you shouldn't notice the overheads so
much.

There isn't one. DJGPP only produces protected mode programs.

No, but you can set up a cross compiler to compile code for *nix.
