Passing input files with @

Tue Nov 7 18:04:00 GMT 2006

Hello list
Following http://gcc.gnu.org/onlinedocs/gcj/Input-and-output-files.html, 
I can specify the source with a file containing a whitespace-separated 
list of input file names. (gcj --main=Foo @files.list).
How do I escape spaces in filenames? I'm unable to find the source file 
that handles it, no common way like using " or \ works and the 
documentation doesn't say anything about that...
Btw: I think this comment is obsolete:
(Currently, these must all be .java source files, but that may change.)
