Umm, I should have said "filename", given that the variable is
AC_CONFIG_*FILES*...

I suspect that what's happening is that a list of files is being built,
and there's a space at the end of the list, followed by a newline.  The
newline is CRLF, and perl only interprets the LF part as the newline, so
CR is listed as one of the files.  If this happens twice, it could cause
the above message.

Looks like all your mounts are binmode.  A textmode (i.e., CRLF) file on a
binmode mount will contain the extraneous CR characters.  Either try
running off a textmode mount (you can mount just that directory in
textmode, FYI), or run the file through 'd2u' (or countless other filters
for CRLF).

Please configure your mailer to not quote raw e-mail addresses in your
replies -- let's not feed the spam harvesters.  Or, as I'll be saying from
now on, PCYMTNQREAIYR (see <http://cygwin.com/acronyms/#PCYMTNQREAIYR>).
