What happens with the file names "//", "//MACHINE", and "//MACHINE/Share" in Cygwin? Don't they appear to be directories, albeit directories that you can't alter? If not, that suggests a bug in Cygwin. > not all POSIX-compliant hosts have the same semantics for leading // As far as I know the only extant hosts with this problem are Windows-based hosts. Apollo DomainOS <http://apollo.maxnt.co.jp/apollo/english/> was the only other example, but it's dead. I don't know the semantics under the Windows-based hosts, so I'm not qualified to write a general fix. (And if it's too complicated, we probably don't want to maintain it.) That being said, it can't hurt to add the following minor workaround, (which would work on Domain OS anyway :-), so I installed it. 2005-05-05 Paul Eggert <[EMAIL PROTECTED]> * makepath.c (make_path): chdir to "//", not "/", if the file name starts with exactly two slashes.
