The default for RHEL5 is 32bit:

The default for RHEL6 presumably changed to be 64bit like SLES11. To
quote big blue (when talking about RHEL5): "It is logical that the
next version of RHEL would likely move to a 64-bit default."
Right -- but is the change built into the gcc binary? Or is there
some other file/environment-variable or whatever that gcc looks at?
