Well, that's one option (or a variant of it).  The other is to be sure
that the utilities being used to do the building don't assume binary files
if they are required.  In your case, I would say autoconf needs to be 
"ported" to Windows by having the source changed to open files explicitly
in binary mode.  The second option is a better one overall since it solves
the problem so that others won't see them no matter what they do...

I'd tend to agree.

Sounds reasonable to me though I can't comment on whether it (or 
something similar) will be done.
