        Type:  bug       |      Status:  new    
    Priority:  normal    |   Milestone:         
   Component:  Compiler  |     Version:  6.8.2  
    Severity:  normal    |    Keywords:         
  Difficulty:  Unknown   |    Testcase:         
Architecture:  x86       |          Os:  Windows
-------------------------+--------------------------------------------------
 Creating a DLL using the -shared option does not work for me:

 1. ghc tries to create a static library (foobar.dll.a).

 2. The linker complains about missing symbols.

 Building an executable from the same project works fine and the resulting
 executable runs all unit tests without errors.

 With 6.6 and the --mk-dll option, the DLL was built without problems.
