Hi, Thank you for poining out the warning on Win64 platform and the analysis. I want to take a look, could you give me the information about your development environment to reproduce this issue? The messages you see look like by gcc.
I've ever worked for a few LP64 systems of Unix and Mac OS X, but never worked for Win64.
