There has to be a simple explanation for this. I've tried to compile the
following code several times, but the compiler doesn't recognize the SetTimer
identifier. Each time I've tried the following compiler settings:

 dmd timer.d gdi32.lib user32.lib winsamp.def

The msdn site says that SetTimer is defined under user32.lib.
the error that I get in return is as follows:

 timer.d(46): undefined identifier SetTimer
 timer.d(46): function expected before (), not SetTimer of type int

Listed here is the source code:

The windows headers supplied with DMD are horribly incomplete. More 
complete ones are available in the win32 section of the bindings project 
at www.dsource.org.
