Description:
mtr doesn't work with the current cygwin (1.7).
Here's what I get on failing tests : 
$ perl mysql-test-run.pl suite/rpl/t/rpl_trigger.test

Convert Unix and Windows format paths, or output system path information

Output type options:
  -d, --dos             print DOS (short) form of NAMEs (C:\PROGRA~1\)
  -m, --mixed           like --windows, but with regular slashes (C:/WINNT)
  -M, --mode            report on mode of file (binmode or textmode)
  -u, --unix            (default) print Unix form of NAMEs (/cygdrive/c/winnt)
  -w, --windows         print Windows form of NAMEs (C:\WINNT)
  -t, --type TYPE       print TYPE form: 'dos', 'mixed', 'unix', or 'windows'
Path conversion options:
  -a, --absolute        output absolute path
  -l, --long-name       print Windows long form of NAMEs (with -w, -m only)
  -p, --path            NAME is a PATH list (i.e., '/bin:/usr/bin')
  -s, --short-name      print DOS (short) form of NAMEs (with -w, -m only)
  -C, --codepage CP     print DOS, Windows, or mixed pathname in Windows
                        codepage CP.  CP can be a numeric codepage identifier,
                        or one of the reserved words ANSI, OEM, or UTF8.
                        If this option is missing, cygpath defaults to the
                        character set defined by the current locale.
System information:
  -A, --allusers        use `All Users' instead of current user for -D, -O, -P
  -D, --desktop         output `Desktop' directory and exit
  -H, --homeroot        output `Profiles' directory (home root) and exit
  -O, --mydocs          output `My Documents' directory and exit
  -P, --smprograms      output Start Menu `Programs' directory and exit
  -S, --sysdir          output system directory and exit
  -W, --windir          output `Windows' directory and exit
  -F, --folder ID       output special folder with numeric ID and exit
Try `cygpath --help' for more information.

How to repeat:
run a failing test on a debug version of MySQL

Suggested fix:
don't use cygpath -y

I got different behavior on Vista X64:

$ perl mysql-test-run.pl suite/rpl/t/rpl_trigger.test
cygwin warning:
  MS-DOS style path detected: C:\ProgramData
  Preferred POSIX equivalent is: /cygdrive/c/ProgramData
  CYGWIN environment variable option "nodosfilewarning" turns off this warning.

Thank you for the report.

I can not repeat described behavior too.

Bjorn, having your feedback probably status of this bug should be "Verified" or "Assigned" still? So we can document documentation and/or MTR will be fixed?

I faced this issue today, I am able to run mtr but with  lots of warnings

can't redirect STDERR to '//./NUL': No such file or directory at mysql-test-run.

cygwin version is : 1.7.1-1

I can not repeat this with 5.1.44 under recent Cygwin on XP. Moreover, I do not see (was unable to ind) any place in the code where cygpath is called with -y command line option.

3 members of Bugs Analysis could not repeat this problem with Cygwin 1.7, so this should be in "Can't repeat" status. I also see no reference to cygpath -y in current sources. If you are not agree with status please provide additional circumstances bug is repeatable under and reopen the report.
