Ok, I've found the problem. msvc doesn't create an import lib because no
symbols are exported. There are two solutions for this
a) use a modified ICE-DEF.cpp and give this to the linker
b) export them with declspec __dllexport()

I prefer the second one because this is used everywhere else too and gcc
also can handle this with __attribute("visible").
For the first solution I also don't know how to tell SCons that there is
an additional dependency file (atm I have to delete the whole cache to
force a relink when the def-file is changed)
