The following sentence that you snipped was

                              I don't much care what, but its build time
    multiplied by 5 needs to not be hellishly long.

and in another message, you wrote

    compiling Qt without -ftime-report takes about an hour (and about
    thrice that time with -ftime-report) on my pentium 4 (2GHz) box
    running a GNU/Linux system.

Five hours falls into the hellishly long category.

But there may be hope:  how much time does "no fancy things" shave from
that hour of build time?  If building the non-fancy parts of Qt only takes
10 minutes, then that's a very viable option.

Alternatively, I could dedicate the machine to doing some really long
build five times over, but only once a week.  This may not be as useful;
you guys decide.
