The problem with Quartus is that it's awfully expensive and has
always been very fragile (particularly on Windows hosts). We've
managed to extract just the Quartus pieces required to build
eCos -- those pieces don't seem to require a registered Quartus
license to run, but it's probably illegal anyway. Actually, we
never did get some of the Perl scripts to work right on some
hosts, so I re-wrote them as bash shell-scripts.

The subset of Quartus required to build eCos isn't all that
huge, so we just dumped a snapshot of that into our archive.
FWIW, I believe that eCosCentric has completed a normal eCos
port for NIOS2 that doesn't require Quartus, and it's available
for free download to anybody with a registered copy of Quartus.
Yes, to get a copy of eCos that doesn't require Quartus, you
have to buy a copy of Quartus anyway -- but at least you don't
have to use it.
IMO, Altera's requirement that all software developers install
Quartus was a fatal mistake.
