Buiding both 32 and 64 bit windows on 64 bit windows machine

This seems to be asked a lot, but I haven’t found a good answer, it seems. I’m running the Windows 7 ×64 Build Environment console. If I use: configure -debug-and-release -platform win32-msvc2010 does it build 32 bits or 64 bits by default? If I want to build 32 or 64 bits explicitly do I put something on the command line for -arch? seems my only choice is “windows” but that’s not really an architecture…. I tried -arch x86_64 but got a link error in the qatomic……code. Thanks Rick
