System: PII 300, NT 4.0 SP3, 64 Megs, Cygwin 19 (latest coolview), FAT partition.

More information on the problem described below:

I create a directory, and then copy a large number (50+) of files into it.
The files are all chmod to 400 (-r--------).  In TCSH if I keep doing
an "rm -rf *" and then "^C" to stop it, then "ls -l" then restart the rm,
periodically, I get permissions changed on files.  Sometimes the
files become 444 (-r--r--r--) and sometimes they get the character
device attribute attached (crw-rw-rw).  After the permission change,
if I do the rm and hit "^C" quickly, the files usually revert back to normal.
Why are the permissions changing?  Is it because I only have FAT 
partitions?

For some time now, I was thinking this only happened in a shared
directory when someone was using the file from a remore machine.
I just found out that this is not the case.  When files get the character
device attribute added, a lot of the cygwin programs (like make) barf.

Ideas?
