Well, the future is 64, so I recompiled all needed
libraries for 64bit and everything works now.

If I would spend money for ccl,
your right, I propably would spend it
on other more needed parts.

Thank you for the fast reply, Louis.

32-bit CCL on Windows tests on startup for the presence of
functionality that it needs; this functionality (the ability
to influence where x86 segment registers point) isn't present
in 64-bit versions of Windows.

We could disable the test (or add a command-line option to do so);
that's easy.  It's somewhat harder to work around the fact that
functionality and to make some fairly deep changes to the win32
version of CCL (and, for extra credit, to make these change in
a way that doesn't negatively impact other platforms or make things
significantly harder to maintain.)

It's obviously desirable to do this (and has been for the last year
or two); it's not a huge project (probably a week or two's work, most
of it more mind-numbing than challenging).  If someone's looking for
a low-level CCL systems programming project, let me know and I'll try
to explain the issues in greater detail.  Otherwise, I imagine that
Gail or Matt or I will get to it someday, but that's been the plan for
a couple of years and it's hard to say how soon someday'll be.

(Yes, I realize that this is important.  If it's important enough to
someone that a few weeks' work can be funded, that'd obviously make
it happen quicker.)
