BUG - error when compiling ratop

[elof2 at sentor.se]

I compiled argus-clients-3.0.5.5 on a linux Debian machine and at the end 
of the compilation it says:
...

All other ra-tools are compiled without problems. It is only ratop that 
complain.

I have not analyzed this.

PS: On my FreeBSD box it compiled without problems.
