A Solaris installation contains ALWAYS 32 and 64 bits libraries. So in any Solaris you can run 32/64 bits programs, and compile in 32 and 64 bits. For this, libraries are stores in "/usr/lib", for instance, for 32 bits, while the same 64 bits libraries are stored in "/usr/lib/64". Currently, python do not considerate this. We have Solaris 10 buildslaves, but they compile in 32 bits, aparently. For instance <http://www.python.org/dev/buildbot/all/builders/sparc%20solaris10%20gcc%203.x/builds/2163/steps/configure/logs/stdio>. We now have 32 and 64 bits OpenIndiana buildslaves, so we can actually check this. They were deployed yesterday. Apparently the changes would be pretty simple, adding ".../64" to library paths, to try to find the extra libraries. What do you think?.

Are you asking about buildbots only or as a general policy? If you are asking about the buildbots then I definitely think we should use 64 bits. If you are asking about policy I would say it should be an option in case people are using C extensions that are not designed to work with 64 bits.
