In the end, at around about 11:45 PM, I gave up waiting so I could go to 
bed instead. It then took an additional hour or so this morning.

So, in total... hmm... maybe 4 hours? Something of that order.

Remember this is running on a *laptop* that's some 6 years old now. It's 
powered by an AMD Mobile Athlon XP 1400+ CPU. It's not even 64-bit. 
(Mercifully, it *does* have a decent amount of RAM though. I upgraded it 
a while back.)

Anyway, I just made the mistake of running the compiler validation 
script. The first thing this does is... clean the build tree. That is, 
it deletes everything and recompiles from scratch. I guess the idea is 
if you're been working on the compiler all day and you think it should 
work now, it does a full rebuild from scratch to check it really *does* 
work and it's not just that you're using an old result.

Rebuild started at 10:30 AM. We'll see how long it takes to rebuild. :-/

(Of course, as well as compiling the compiler twice, it also compiles 
all sorts of other build tools, the standard libraries twice, builds 
HTML documentation, and sweeps your bedroom floor...)
