Error installing Nessus on AIX 5.1

[Dagamier]

I've been trying to get nessus installed on my AIX box but have been
running into problems. Not sure if maybe there's a syntax error in the
header file (the parse error bit) or maybe the error is somewhere
else. Don't want to go hunting through the header files just yet in
case someone has stumbled up this before.
