Hello,

im running a complete Cygwin installation from
2007-02-04 on a Windows XP pro PC, and
it works well so far.

I have the following behaviour:
############## snip ##################
$ mount
c:\cygwin\usr\X11R6\lib\X11\fonts on /usr/X11R6/lib/X11/fonts type 
system (binmode)
C:\cygwin\bin on /usr/bin type system (textmode)
C:\cygwin\lib on /usr/lib type system (textmode)
c:\cygwin\tmp on /tmp type system (binmode)
C:\cygwin on / type system (textmode)
c: on /c type system (textmode)
$ pwd
/home/es_sv
$ echo peng >p.txt && CO=$(cat p.txt) && od -c <<<"$CO"
0000000   p   e   n   g  \r  \n
0000006
############## snip ##################

I expected the the od output 'p  e  n  g  \n' with no
\r in front of the \n.
The file p.txt resides in a directory with textmode
mounting, so I can not see any reason, why cat
reads the file in binary mode.

I think this is a contradiction to Cygwin User's Guide,
chapter "Text and Binary modes", where I found
the statements "Most other programs (such as cat,
cmp, tr) use the default mode." and "If the filename is
specified as a POSIX path and it appears to reside
on a file system that is mounted (i.e. if its pathname
starts with a directory displayed by mount), then the
default is specified by the mount flag."

Is this a bug or am I wrong?
Thanks for any answer.

Best regards,
Sven
