Most of applications have 32 and 64-bit variants, unless they stuck in 
the 90's. Defaulting nowdays to 32 bits is simply unreasonable. If 
someone wants to target an outdated architecture (and 32-bit x86 really 
is a separate architecture, including hardware features and software 
ABI) then let them do that with a little more effort. The rest of the 
world have moved to 64 bits long ago, and that is what we should target 
by default, IMO.
