Are you referrring to

http://finzi.psych.upenn.edu/R/Rhelp02a/archive/66941.html

?  Unfortunately I never received a reply to those questions.

This appeared to be something new in AIX 5.3's headers, most likely that 
they have apparently started defining SOCKLEN_T.  For the R-devel version 
on R we changed to R_SOCKLEN_T.

So please try the R-devel version of R, or change all occurrences of
SOCKLEN_T to R_SOCKLEN_T.

Googling showed that several other projects had been affected by this. 
E.g.  http://www.zsh.org/mla/workers/2004/msg01205.html
And socklen_t on AIX has been an age-old problem.
