That's the confusing thing - everything looks right with the DLL macros.

The IlmBase libraries all have OPENEXR_DLL set, and the appropriate 
XXX_EXPORTS set. The relevant XXXExport.h headers all show 
XXX_EXPORT_DEFINITION ending up as __declspec(dllexport) where 
appropriate, and __declspec(dllimport) when included in IlmImf.

Anything else worth checking?
