[Ecls-list] Some bugs and a question.

I checked out ecls from cvs about 5 hours ago:
(ECL (Embeddable Common-Lisp) 0.9i (CVS 2007-12-22 16:55) on Ubuntu 7.10 amd64.)

First my question: I'm wanting to use ecl to make a lisp library
accessible to C.  I've read through some of the new-manual and am
trying to decipher the threads example.   Is this the best example for
what I want to do? Are there any other examples?

Some bugs:

1. configure doesn't complain when you don't have libgmp installed
(you find that out on make instead).

2. When loading a successfully compiled file, I get complaints that
"fixnum is not a class", when I have methods specialised to fixnum.
The workaround of #+ecl integer #-ecl fixnum seems to work.  It's
obviously a bug because the file compiled okay (and fixnum
specialisation works on numerous other CL's).

3. The c package doesn't get autoloaded unless you compile-file first.
 This means that e.g. c:build-fasl et al. fails:
> (c:build-fasl "myecl" :lisp-files '("hello.o"))
There is no package with the name C.

4. http://ecls.sourceforge.net/new-manual/ch22s07.html doesn't seem to exist.

5. ecl-config line 36 should probably be:
  echo "-Dlinux   -I/usr/local/include/ecl/"
instead of
  echo "-Dlinux   -I/usr/local/include/"
OR examples/threads/import/import.c:43 should be:
#include <ecl/ecl.h>
Probably the latter.

6. After fixing import.c:62 to:
I got the import example to work, however, it stalls with:
5Collecting from unknown thread.
