The message I was getting was
fixme:file:wine_nt_to_unix_file_name UNC name L"\\??\\UNC\\machine\path"
so I had a look in the code and found the relevant place, added a few printfs and found that that
\\machine\path
maps to
.wine/dosdevices/unc/MACHINE/PATH
so it is supported, it just doesn't seem to be documented anywhere that I could find. Everything is working nicely now.
I'll write a quick FAQ entry if I get time today. Thanks,
Cool! You're right, this does appear to be totally undocumented, I had no idea about this. It should probably go into winecfg and the man pages.
