[Dev-C++] InitCommonControls() Problem

Hi everyone, 

I get the following error messages when trying to compile my project that
uses "CommonControls":
[Basically a small program that uses a ToolBar...]

 - C:\Dev-Cpp\Projects\MenuBar.o [Warning] In function `WinMain':
 - [Linker error] undefined reference to `InitCommonControls@0' 
 - [Linker error] undefined reference to `CreateToolbarEx@52'
 - C:\Dev-Cpp\Projects\Makefile.win [Build Error]  [MenuBar.exe] Error 1

I have included the Header file <commctrl.h>

In WinMain() if have done the following...
---
InitToolbar();                [this is the method that I use to initialize
the ToolBars structure]
InitCommonControls(); 

tbwnd = CreateToolbarEx(hwnd,
                WS_VISIBLE | WS_CHILD | WS_BORDER,
                ID_TOOLBAR,
                NUMBUTTONS,
                hThisInstance,
                IDTB_BMP,
                tbButtons,
                NUMBUTTONS,
                0, 0, 16, 16, 
                sizeof(TBBUTTON));
----
I don't recieve any other error messages and my Resource file and Header
file are all in order.

If you have any ideas on how I can solve this problem, please let me know.
Thanks, 
Megan.
