You need:

  cc -mwindows hellowin.c -o hellowin.exe -s -lwinmm

The -mwindows gets you the GDI references, such as GetStockObject;
-lwinmm is for PlaySound, (which I learned by reading
http://msdn.microsoft.com/en-us/library/windows/desktop/dd743680%28v=vs.85%29.aspx
to see which library is needed).
