dll name length (was: Windows dll replacement with Linux library)

[Dan Timis]

I finally figured out what my problem was.  If the name of the library 
is "USBUtils" it works, if it is "USBDeviceUtils" it doesn't.  Actually 
the max length I can use is 11 characters.  That is probably 15 
characters including ".dll"

In my config file all filesystems are "win95"  The version is "nt40"

Is there any way to configure wine to support longer names?

Thanks,

Eric is right, I've run into the same problem (with visual-mingw)
some time ago. He fixed it way back in Sep, 2004, with this patch:

http://www.winehq.org/hypermail/wine-patches/2003/09/0174.html

If you can't update to something newer, this patch is trivial
to backport in your tree. Please let us know if it helped.

Thanks.

I will try it and tell you if it worked.  It may take a couple of weeks 
since we are frantically preparing for a trade show, then going to the 
trade show.
