issues on FreeBSD 5.4

[Lei Wei]

Hello,

I'm trying to install argus2.0.6 on FreeBSD 5.4. When I did make, there 
were some compile errors like:

### Making in /home/lwei/files/argus-2.0.6/common

It seems to have some type conflicting errors and at the end, the 
"argus_common.a." error. Could anybody give me some help on how to deal 
with this? Any help will be appreciated.
Thank you.
