In this version, I decided to include all codes together. Another
possibility would be to omit completely the codes that exist only on one
system, or to put them in a separate table.

The BSD, macos, windows and BeOS column come from the mail Michael has found
yesterday. I did not re-check it much.

Some systems are missing, Solaris is the obvious example. Patches welcome.

Regards,
