problem with windows gui program

[Henry K. H. Cheung]

Hi:

I'm new to this.  How do you compile and link a windows program?  I've
this (simplew32.c):

#include <windows.h>
#include <stdio.h>

int STDCALL
WinMain (HINSTANCE hInst, HINSTANCE hPrev, LPSTR lpCmd, int nShow)
{
 char text[80];

  MessageBox (NULL, text, "Test", MB_OK);
  return 0;
}

and when I use bash this on NT4 (Cygnwin32 Beta 19) with
    'gcc -o simplew32.exe simplew32.c -lgdi32'

I got this:
c:\temp\cc0010481.o(.text+0x1c):simplew32.c: undefined reference to
'MessageBoxA@16'

Please help.

Thanks.
