I agree with you, but it worked with old version of cygwin.
Get the possibility to tune binmode/textmode of Window path for cygwin 
application looks like important to me.


The greet things with cygwin is to mix windows and unix world. I don't know 
the history of cygwin, but I may suppose that the option "mount -t" was 
here to get this compatibility between unix and windows.
Most of the time I use the cygwin make, sed, grep, diff, cvs in combination 
with  (only) windows development tools ( especially armcc ). I use "cygpath 
-m" to get compatible path for both environment. I can't use it now.

issue #1:
I start to look at this problem when tkcvs was not able any more to perform 
a diff between 2 version.  tkdiff, copy the cvs HEAD release of a version 
in temporary directory, then call the cygwin 'diff' to perform the 
comparaison. diff compare the local file (text mode) with the one in temp 
directory (c:/tmp/xxxx, so in binmode)

issue #2:
even whith cygwin "tclsh"  version,
    glob /*
returns
    C:/cygwin/bin C:/cygwin/cygwin.bat C:/cygwin/cygwin.ico ....

issue #3:
Another example: the 2 following lines don't gives the same result
     cd c:/ && grep XXXX file
     grep XXXX c:/file
