Libffi has been ported to many different platforms, although this

Libffi has been tested with the <a
|
|

href="http://www.cygnus.com/egcs/">egcs</a> 1.0.2 gcc

compiler. Chances are that other versions will work. Libffi has also

been built and tested with the SGI compiler tools.

|
|

If you port libffi to another platform, please let me know! I assume

|

that some will be easy (x86 NetBSD), and others will be more difficult

(HP, AIX).
