Typically -l appends the necessary extension itself (.lib on  
Windows, .a or .so on Unix, .a or .dylib on OSX).  You may also need - 
L. (again, no space) to make it check the current directory.

It may be easier to see if ghc has an option to pass through the next  
argument straight to the linker, or even recognizes .lib files and  
passes them through unchanged (then you'd not need any option to  
include it, just the filename).  Unfortunately my knowledge of ghc on  
Windows is rather sketchy.
