Hi,

I'm running "CYGWIN_NT-5.1 1.5.24(0.156/4/2) 2007-01-31 10:57".

If I try to create a regular file with a colon (:) in its name, cygwin 
refuses it with ENOENT (rightly so):

     $ echo test >"a:b"
     -bash: a:b: No such file or directory

However, if I put, in addition, a slash in the name:

     (
       set -e -C -x

       mkdir test
       df -m test
       dd if=/dev/zero bs=4096 count=1024 >'test/a:b'
       df -m test
       ls -lsn 'test/a:b'
       ls -lsn test
     )

Standard output and error:

     + mkdir test

     + df -m test
     Filesystem           1M-blocks      Used Available Use% Mounted on
     C:\cygwin                57232      9100     48132  16% /

(Redirection not shown below)

     + dd if=/dev/zero bs=4096 count=1024
     1024+0 records in
     1024+0 records out
     4194304 bytes (4.2 MB) copied, 0.08 s, 52.4 MB/s

     + df -m test
     Filesystem           1M-blocks      Used Available Use% Mounted on
     C:\cygwin                57232      9104     48128  16% /

     + ls -lsn test/a:b
     4096 -rw------- 1 1003 513 4194304 Oct 16 16:14 test/a:b

No problem until this point, but:

     + ls -lsn test
     total 0
     0 -rw------- 1 1003 513 0 Oct 16 16:14 a

Shouldn't the redirection used with the dd command fail with ENOENT? The 
file system containing the directory "test" is mounted without the 
"managed" mount option.

This doesn't depend on the shell, I can reproduce it with a simple C 
program.

Thank you
lacos
