proposal for changing name mangling.

[Michel Stoop]

I have again ran into troubles with duplicate mangled names under W2k.
We have some model libraries wich contain more than 4000 files
with simmilair names. (like gatkr160x400.mod).
Now when I type in a cmd prompt: del gat*.mod I get some errors.
After some research I saw that the delete command builds it file list
on the mangled name. I assume to save memory...
What I also saw that when I copy these files to a NT server I get
mangled names consisting of the 2 first characters in uppercase, then
a 4 character hex value, then the mangling char and a number.
This gave me the idea to change the way samba mangles names to match
what W2k produces. So I did some work on smbd/mangle.c
With the currrent name mangling of samba I got up to 6 equal mangled
names for different files, but now I get only unique names.

So in the current version the file gatkr160x400.mod would be mangled
to GATKR~9 at .MOD, but now it becomes GA494F~6.MOD
Now I have included a diff file for samba-2.2.3a and want to ask if someone
wants to look at it. And I want to know what the samba team thinks about
changing the way names are mangled and how it should be implemented.
