...just provide a way to turn it off. :-)

I build on one box for an entire platform (e.g. "x86/Linux" is a "platform"). Except for Linux, I think it is safe to switch to 64-bit builds for all of them (where applicable). For Linux, I build on a 32-bit-only box that can't produce 64-bit binaries anyway. But someone else might need to build 32-bit packages on a 64-bit box.

Otherwise I would be in favor of this, not just for time-related stuff but any time building 32-bit is a needless limitation. For example, programs that might be memory-hungry (sort comes to mind). Also because, despite the pundits, 64-bit does seem to be slightly faster (at least compared to a 32-bit build of the same program on the same machine).
