[Help-bash] Filename Nch-cs-hymn.t2tt and nch-cs-Hymn.t2tt treated as the same

[Barrie Stott]

Look at the following lines:

gbs:nch $ ls -l *.t2tt
-rw-r--r--  1 gbs  staff  3580 14 Feb 11:32 Nch-cs-hymn-author.t2tt
gbs:nch $ touch nch-cs-Hymn-author.t2tt
gbs:nch $ ls -l *.t2tt
-rw-r--r--  1 gbs  staff  3580 14 Feb 12:34 Nch-cs-hymn-author.t2tt
gbs:nch $ 

This is a small example that exhibits my problem.
1. The time of Nch-cs-hymn-author.t2tt in the 1st 'ls -l' is 11:32.
2. I touch nch-cs-Hymn-author.t2tt that the 1st 'ls -l' says doesn't exist.
3. Nothing says there is an error so I accept it.
4. I expect 2 files to be listed by the 2nd 'ls -l' but get the same file whose 
time has    
   increased by about an hour.

It appears to me that bash thinks that the 2 files are the same so am I wrong 
in thinking the filenames refer to different files.

I am running OS X 10.6.8 and the bash version is shown below.

gbs:nch $ bash --version
