[R] LAPACK.dll and Excel with R 2.7.0

I was building a R addin for Excel. I was able to build R.dll, export to
Rdll.lib and wrap it in a Excel addin (.xll) format. Most basic
functions work fine within Excel except functions that use LAPACK, e.g.
eigen, solve etc. But if you use solve(..., LINPACK = T). That's fine.

So apparently the problem is with loading the shared library
../modules/lapack.dll. I read one of the earlier threads on this issue
with Rexcel with R earlier than 1.7.1. I am not sure if anyone has seen
similar problem?

Thanks in advance!

Best Regards,
