So maybe it's because I'm using this version of the compiler that I 
built myself, and it's broken in some way?

Er, no. Just tried it with the release version. The numbers are a 
fraction of a second slower still. Either way, two equivilent 
formulations of the program have wildly different runtimes.

Interestingly, on my much more powerful desktop PC [with yet another 
version of the compiler], the "slow" version only takes 2 seconds. But 
the "fast" version is too quick to time, so something is still wrong.

Ah, the bitter taste of utter defeat.
