self-evident, I'd have thought.

these days we have debug functionality for this kind of thing, so you
don't need to recompile; you should just need to set debug_ to 1
for the appropriate object you're interested in.

if (debug_) {
 /* printf blah etc. */

}

selectively commenting out/uncommenting printf's and recompiling is
stone-age. Having said that, these messages aren't strictly debugging
messages - a verbose_ flag, anyone?
