Subject: | File::Copy copy function should use sysopen instead of open |
On Windows, there are reserved filenames, e.g. "aux.txt" that are prefixed by device names.
It is possible to create files/directories, as long as they are escaped, e.g. \\.\C:\some\dirs\aux.txt
But Perl''s open() function cannot open these files. They can be opened using sysopen.
