DOS ain't dead

Ahoj,

New mutt email clients uses severall files with symlinks in temporary directory

The /temp is broken in FreeDOS on FAT32, mutt can`t reach files :(
Do You have any idea, how to fix symlinks and temporary files in new mutt?

Thanks David

So, you mean, Mutt relies on the name of the files to work correctly?

Can you provide a DOS binary for testing by others?

> The /temp is broken in FreeDOS on FAT32, mutt can`t reach files :(

Please test on FAT16.
Which FreeDOS version did you use?
Does it work on any other DOS?

You probably need to code a mapping between "more DOS-style filenames" and the one, Mutt expects.

Robert uploaded testing mutt for short time!

It depends on libintl.DXE (missing).

DOS gives me freedom to unlimited HW access.

Isn't that in gtx1981b.zip? (GNU gettext, 12 MB)
