Thanks for the fix! Works perfectly now.

I checked out the latest version of CFFI and worked with the code in there.
That compiles if I apply the following patch:
diff -rN old-cffi/src/cffi-abcl.lisp new-cffi/src/cffi-abcl.lisp

The :calling-convention keyword seems to be replaced by :convention.
I don't use CFFI directly but it is used by cl-sqlite. This seams to work,
although I have some problem with the FIXNUM size. Untill I figure out what
in cl-sqlite causes that I cannot tell much more, but ABCL works just fine.
I tried to run the test-suite in TRIVIAL-FEATURES (it uses cffi for its
tests) but that doesn't work. It looks like it is related to cffi-grovel but
I didn't exactly understand what was going on there. I guess grovel needs
something added for ABCL because it works in other Lisps.
I would be interested in getting CFFI working for ABCL because that would
make my application run in ABCL. If I can help in any way please let me

Thanks again. Building from Netbeans works fine now
