Are you using LDC? That's the only way I've been able to create a 
working DLL. I've never had to add the -defaultlib option with 
LDC on Windows. Here's a post describing all the steps I took to 
make a DLL that can be called from R:

The references to R are not important. Should be straightforward 
to adopt for your use case.
