snapapi 0.7.24 compile under Slackware 12

I'm trying to compile trueimage agent on slackware 12 with no success.

First, i have installed dkms on the server and followed instructions found here: https://www.wilderssecurity.com/showthread.php?t=173463 (HOWTO: Install Acronis on Ubuntu 7.04)

I tried with slack vanilla kernel 2.6.21.5 and also with a custom 2.6.23.
dkms in both cases fails to compile modules:

The make.log:

It contains more than thoose in quote, but i think its clear from the beginning of the log file that there is a problem at least with some paths.

My kernel sources are in place: /usr/src/linux
Since devs have removed config.h from 2.6.19 or so, a touch a config.h in /usr/src/linux/include/linux/
All the other headers are in place also (posix_types.h, types.h and so on).

I have tried also with arch=686 with no luck, always the same error.

Is there any solution on this, or maybe someone who managed to compile snapapi modules on slackware 12?

PS. i'v tried and 0.7.5 also with no luck

edit: version 0.7.10 gives the error bellow:

Thanks in advance

 

I tried again and solved the path problems by making some changes in Makefile on 0.7.24, but again it hits wall:

gcc version 4.1.2

Is there anyone who managed to compile snapapi with gcc 4.1?

 

Finally i managed to compile snapapi 0.7.24 but only when i downgraded to 2.6.18.
It was not gcc the problem.

So i revise my question -sorry for any inconvenience-, does anyone manage to compile it with a latest kernel or is there any update availlable?
It's not acceptable to downgrade a lot of servers to older kernels.

Thanks
