 When I compile attached files all at once they link fine:
   $ ghc A.hs B.hs Main.hs
   Linking Main.exe ...
 But with separate compilation they produce link errors:
   $ rm -f *.o *.hi
   $ ghc -c A.hs
   $ ghc -c B.hs
   $ ghc -c Main.hs
   $ ghc A.o B.o Main.o
   B.o:fake:(.text+0x34): undefined reference to
 `vectorzm0zi10zi11zi0_DataziVector_fromList_closure'
   B.o:fake:(.data+0x20): undefined reference to
 `vectorzm0zi10zi11zi0_DataziVector_fromList_closure'

 I'm using the latest Haskell Platform 2014.2.0.0 for Windows.
