Actually I tried, but it did not seem to work, and more seriously, when *using* the library (that is when there are some __declspec(dllimport)), the compiler often report internal errors ...

I was trying on a complete library, but to track down the problem I'm now going to try on simple examples ...

Thanks for the help !
