I don't know any programs other than shells that would do so. FPC  
itself doesn't do anything like that either, and hence would complain  
that it couldn't find a file with such a name (quotes are valid  
characters in file names, at least on Unix-like OSes).

In general, such things are only done if the parameters are passed on  
to a shell, because that one will again process quotes (and then it  
could be required if "outputfile.org" contains spaces).
