If we could come up with a reliable way to distinguish between the two, 
I suppose we could use the abovementioned message on bi-arch platforms 
and some other message (e.g., "Wouldn't it be better to build for a 
platform that won't stop working in 2038?") on 32-bit time_t only 
platforms. If not, the diagnostic is likely good enough as-is. Anybody 
who's building for these obsolescent platforms should know they're 
obsolescent and not bi-arch and can simply ignore the question.

Doesn't removing this line suppress the suggestion even for bi-arch 
systems where the suggestion is useful? That seems like a step backwards.
