Allegro 7.0 isn't currently supported yet by us.  If there is enough
demand we'll port the Allegro 6.2 stuff to it.  Is there a pressing
need for it?  We usually use SBCL.

In all honestly I don't know.  I work with FreeBSD.  On Fedora systems
it was necessary to include this library, so I assumed it was a linux
thing.

I guess the Allegro compiler is more picky than the SBCL one.

This one is mind-boggling.  The two tests no-eval-initform and
update-class should fail, they were fixed in the CVS release.  However
I have never seem arrays-1 fail, unless just about everything else
does.  The only thing I can imagine is this having something to do
with upgraded-array-element-types.  Unfortunately I haven't tested on
Allegro 7.0.

This is also a little perplexing.  Can you provide more details on the
test failures?  We're running 19a over here and it seems to pass the
tests, though maybe there are patches you're running we're not?

Thanks for the detailed bug report.

Take care, B
