D'oh!  Alas, the tick is practically invisible to me on the web page, 
and I had my prescription for glasses checked recently :-)  I'll 
remember it's there, though.

Fair enough.  Do library maintainers normally use Cabal to do routine 
builds and rebuilds of their own libraries?  If so, do people simply 
keep locally modified .cabal files around for this kind of thing?

By the way, when I spent a bit more time poking around at this, I found 
that even adding -auto-all left me with empty cost centres in profile 
output for libraries (but not the main app) on x86_64, but everything 
was fine on i386.  I'm unfamiliar enough with the territory that I don't 
know quite what to do with this piece of information.  What would be 
useful for you to know if I were to file a bug?

I'll be sure to check it out.  Thank you.
