Little by little I'll start shoving all syscall-related compatibility code into a C library called libfixposix - http://gitorious.org/libfixposix/libfixposix - on which iolib will depend.

I've decided to do it mainly because writing OS compatibility code is much easier in C and with the use of autoconf and because CFFI .so wrappers cause problems with deployment/static executables.

Until this is finished, sources will be a little unstable so please stick with the 0.7.0 release, or if you feel adventurous test libfixposix and iolib, especially on *BSD and OSX.

Hi,

with an iolib snapshot and sbcl I got the following errors:
