Hi,
    I'm trying to create an emulator for the Multitech Micro-Professor
MPF-IB and I'm having a few problems with Djgpp. If I try to build the code,
I end up with the following error output from my makefile:

---8<---CUT HERE---8<---
gcc -Wall -O3 -m486   -c -o mpf.o mpf.c
mpf.c: In function `drawLEDSeg':
mpf.c:61: warning: passing arg 3 of `polygon' discards qualifiers from
pointer target type

gcc mpf.o emuutils.o raze.o -o mpf.exe -lalleg
---8<---CUT HERE---8<---

Someone care to explain this? I've managed to create a short program that
demonstrates this.

Compiler cmdline:
    gcc -o temp.exe temp.c -lalleg

---8<---CUT HERE---8<---  TEMP.C
#include "allegro.h"
#include "conio.h"

const int points[12] = {1,2,3,4,5,6,7,8,9,10,11,12};

int main()
{
   allegro_init();
   polygon(screen, 6, points, 15);
   getch();
}
---8<---CUT HERE---8<--- TEMP.C

Thanks.
