CFFI patches for ABCL ​http://slack.net/~evenson/abcl/cffi-abcl-20101231a.diff

CFFI needs jna.jar

​https://jna.dev.java.net/source/browse/*checkout*/jna/tags/3.2.7/jnalib/dist/jna.jar

which should be save locally, say at ​file://work/jna/lib/jna.jar.

Then build ABCL with the additional.jars property set

    ~/work/abcl$ ant -find build.xml -Dadditional.jars=../jna/lib/jna.jar

and the resulting 'abcl' or 'abcl.bat' script will be included in the CLASSPATH when ABCL starts.

For adding items dynamically to the classpath see JAVA:ADD-TO-CLASSPATH.
