Which, since it sounds as this is an autotools-driven package, would be
caused by a missing "-module" flag in the corresponding *_la_LDFLAGS.
It won't cause a link error (only on Darwin is there a structural
difference with or without), but it does affect where the DLL is
installed on PE platforms, as you see here.

Furthermore, since -module is missing, that means the module library
name must start with "lib" (since automake would complain otherwise).
The resulting DLL will start with "cyg" instead, meaning that whatever
is loading this module needs to be edited appropriately.
