39 It is an estimate (a prediction) so it's subject to change.

44 Probably, I don't know if genlop takes that into account. But there's countless
45 factors that affect build time that it's practically impossible to predict
46 accurately. So it means nothing.

48 Does that estimate even look reasonable to you?
49 gnutls compiles in a few minutes but gcc takes significantly longer for me.
