Thanks all for their comments.  Using ls -@lsflags will give "ls:
invalid option -- @" instead.  I also know of cat and xargs but I just
want to check whether @file is supported _within_ Cygwin or not.  The
insert_file() function inside dcrt0.cc which exists (for quite a long
time) does not seem to work.

Regards,
cheng AT powertv DOT com

Command line length limitations?  Yeah, there's xargs.  I'm not saying
$(cat lsflags) won't do, just that there's some merit in the @ syntax.

But in any case, upon rereading, I see this isn't really what Cheuk is
asking -- the claim is that there's evidence cygwin supports this.  Hmm,
time for the obvious: if the comment really says to use -@file, (i.e.
the dash is not a typo), then I'm not surprised ls @lsflags doesn't do
it.  Have you tried ls -@lsflags ?

Why not simply "ls $(cat lsflags)"?
