[Mono-list] Platform comparison

Actually, as I understand it, it doesn't do any transformation. It passes
/'s to the underlying filesystem API, because it is supported there.  Yes,
the Win32 API *does* support '/' as a path separator character (Explorer's
support for this is sketchy, though; Explorer has other problems as well,
such as not allowing you to rename a file so that it begins with a dot).
Note also that even in Windows, the framework has
System.IO.Path.AltDirectorySeparatorChar == '/'. I haven't investigate it,
but the framework documentation implies that Rotor sets this to "\\",
despite the fact that, to the best of my knowledge, "\\" is not supported
on Unix as it is a valid character within a pathname component! I quote
from the AltDirectorySeparatorChar MSDN article:

The character stored in this field cannot be in InvalidPathChars. This
field can be set to the same value as DirectorySeparatorChar.
AltDirectorySeparatorChar and DirectorySeparatorChar are both valid for
separating directory levels in a path string.

The value of this field is a backslash ('\') on Unix, and a slash ('/') on
Windows and Macintosh operating systems.
