Some functions in these DJGPP headers headers are not portable (some
are, e.g. fgets, but others like clrscr aren't), so you can't use
them under Linux directly. Furthermore, as The Chief said, you can't
use C headers directly...

However, recent releases of GPC come with a set of units which are
both portable and written in Pascal, so that's probably what you
need. For the headers mentioned, you probably want to look into the
GPC, CRT and maybe Dos units. (The Dos unit, despite its name, is
portable as well.)
