Does this mean that you have given up on the problem with Clearcase
volume with 8+3 names?  (Read: can I nuke all the mail we exchanged on
the subject and which I'm keeping for future discussions with you?)
Or are you still trying to see the short names at least?

Can't that DLL export the same LFN API that Windows 9X supports?  That
would make libc immediately compatible, with no need to add any code
bloat.  Is there any problem on NT for a DLL to hook Int 21h?

Doesn't look like to much of a problem to me.  We already have
emu387.dxe, which is the same problem.
