Maybe someone more knowledgeable with linkers can help better, but I 
think that the linker cannot know that these functions are in kernel32.dll.

Do you have kernel32.lib (import library) and kernel32.dll? It should be 
included with the Windows sdk.

http://www.mingw.org/wiki/createimportlibraries shows a way of creating 
an import library from a dll.

Once you have the import library, try adding -lkernel32.lib to the 
linker options in the project options and let's see the result.
