Yea, but that doesn't explain how the "cc" got there in the first place.

OTOH, looks like when I configure gcc without a --target, I get both a
"i686-pc-linux-gnu-gcc" *and* a "gcc".  So we're both right.  :^)

Hmmm, so configure *does* think for the user some.  Scary.

Which is why I have a co-lo server located downtown at my own expense
(being an independent consultant, it's always at my own expense) that
houses my CVS repositories, which I'm religious about.  I do updates
about twice a day.

So if my house does burn down (I had a lightning strike here last
year, but no fire other than the one in my oven and a telephone wire),
I may lose an in-process build and a few drafts, but nothing older
than a few hours.

I couldn't agree more.  But I still don't work as root, so that I can
avoid the lost productivity of doing something stupid.  I can't
prevent an Act of God, but runing as a luser catches pretty much
everything else.

Having grown up on a farm, I've heard lots of scary noises on some
very expensive machines.  But I still don't think I would like to hear
my hard drive coming apart!  :^(

Agreed.  That's partly why I switched to SCSI (I also like the
performance boost).  I'm suspicious that the SCSI drives are built on
the same mechanical base as the IDEs, though, so I'm not sure if I
have really accomplished anything other than going faster until
breakage.  But man, these 10K rpm IBM DeskStar SCIS drives are
schweet!  Bring on the gcc and glibc builds!

Right, enough of that then.
