Sorry, but you are wrong: Windows understands / and \ alike, and it
understands "//servername/" exactly as "\\servername\".

The problem is elsewhere: DJGPP simply does not support UNC-style file
names.  It might work for you in some simple cases, but will
mysteriously fail in others.  The reason for that is that some
file-related functions need to know the drive letter of the volume
where the file resides, and that is just too painful to compute for a
UNC-style file name (and might even not exist in some configurations).
