Patch to build CIPE 1.6.0 for gentoo-sources-2.6.13-r3

A patch for Gentoo users, to make CIPE 1.6.0 build under
gentoo-sources-2.6.13-r3. I hope it will work with a vanilla kernel
too. 

I doubt it will work with earlier versions, it's just a dirty hack from
a java programmer needing to make it work in gentoo with the latest
kernel.

It includes the patch sent by Dick St.Peters <[email protected]>
for the kernel API changes as of kernel 2.6.12.3.

This patches cipe-1.6.0 for compiling with gentoo-sources-2.6.13-r3.

It builds upon the patch sent by Dick St.Peters <[email protected]>
for the kernel API changes as of kernel 2.6.12.3.
