Hi Dave,

I got the following compile error in cpqfcTSinit.c:

The first part of the error message is strange. 2.5.13-dj2 does exactly
the following change to this file:

         // copy the caller's struct to our space.

This is the only place in the 2.5.13-dj2 patch where CAP_RAW_IO is
mentioned and a grep showed that it's the only occurence of CAP_RAW_IO in
the whole 2.5.13-dj2 kernel sources:

You only think this is a free country. Like the US the UK spends a lot of time explaining its a free country because its a police state. Alan Cox
