i586-mingw32-nm didn't show anything at all. But here is the source code below
and the command I use to compile it below that.  Note I have to use main()
instead of int main(), it has something to do with SDL. SDL will complain if
I use anything else.

#include "PowerPak/powerdraw.h"

main(int argc, char *argv[])
{
   /* Initialize the library */
   PD_Init();

   /* Initialize 640x480x16bpp graphics mode */
   PD_SetGFXMode(640, 480, 16, PD_DEFAULT);

   /* Draw a little cylindrical thingie */
   PD_Ellipse(Screen, 320, 100, 100, 50, PD_CreateColor(Screen, 0xFF, 0x00,
0x00));
   PD_Ellipse(Screen, 320, 220, 100, 50, PD_CreateColor(Screen, 0xFF, 0x00,
0x00));
   PD_Ellipse(Screen, 320, 220, 50, 25, PD_CreateColor(Screen, 0xFF, 0x00,
0x00));
   PD_Ellipse(Screen, 320, 380, 50, 25, PD_CreateColor(Screen, 0xFF, 0x00,
0x00));
   PD_VLine(Screen, 100, 220, 220, PD_CreateColor(Screen, 0xFF, 0x00, 0x00));
   PD_VLine(Screen, 100, 220, 420, PD_CreateColor(Screen, 0xFF, 0x00, 0x00));
   PD_VLine(Screen, 220, 380, 270, PD_CreateColor(Screen, 0xFF, 0x00, 0x00));
   PD_VLine(Screen, 220, 380, 370, PD_CreateColor(Screen, 0xFF, 0x00, 0x00));

   /* Wait for 5 seconds so you can see it */
   PD_Wait(5000);

   /* Cleanup */
   PD_Quit();
}

and here is the command to gcc.

 /usr/win32/bin/i586-mingw32-gcc ex1.c -lPD -lSDL -lttf -lIMG
-I/usr/win32/include
