Thomas / (other Mac OSX user)

Ethan Merritt (gnuplot developer) is willing to fix this problem but  
does not have a Mac available to track down the problem.

Unfortunately, I lack the skills needed to debug c/c++ code. If you  
are inclined to assist, see the thread at the link below

http://www.nabble.com/problem-with-%22set-x11-%7Bsize-WW%2CHH%7D-%7Bposition-XX%2CYY%7D%22-to21190071.html

The branch including Ethan's reply dated "Dec 29, 2008; 12:15am" is  
the one to read.
