SetTimer is provided by user32.dll/User32.lib so make certain you are linking
with that 
(should be by default though, I believe).  Also, you may need to include an
extern 
decleration for it, as the Win32 API declerations in Phobos are incomplete. 
(You can look 
through dsource.org for other Win32 offerings, and there's always Tango once it
goes 
public.  Although, honestly, I don't really know the state of its Win32 API
either.)

Thanks. Simply adding an extern statement and a function prototype
seems to have resolved the problem.
