I had another look at Mike Steglich's code and remarks. I noticed two  
things. First, his remark about the command line shell (explained by  
Stefan in a later email) is true. Even if you put double quotes around  
a command line argument, the quotes get stripped before the string is  
put into argV.

Second, however, was the pattern I discovered in OSParseosss.l:

optionValue ([-a-zA-Z./~:_0-9$\?+\\!@#&*()]+|\"[^"\n]*\")

The second part of this pattern explicitly looks for strings enclosed  
in double quotes, so it seems we are already catering for this  
possibility.

If you put a command line argument (any argument) into double quotes  
--- which is legal ---, you are clearly signalling that this argument  
should be handled as one argument, even if it contains spaces, but our  
system splits it apart. So I am thinking that this is a bug in  
OSSolverService.cpp.
