Hi Max,

thanks for your quick response. Indeed, setting the 
POSIXLY_INCORRECT_GETOPT environment variable did the trick and produces 
a result that is in synch with the man page.

Since I don't know anything about the various flavours of getopts around 
and what is posixly correct and what not, and I guess a lot of other 
users don't know neither, how about updating the man pages to be in 
synch with the current behaviour and adding a paragraph on the 
POSIXLY_INCORRECT_GETOPT stuff?


Cheers,
Patrick
