When did Windows start accepting forward slash as a path separator?

That's not entirely true, in WinNT derivatives the backslash is the  
real seperator at the kernel level, the Win32 perform some conversion  
that allows forward slashes and recognizes special files like CON, PRN,  
et.al..

To make live even more interesting, only unicode paths with backslashes  
as seperators can address all files (at least when I last looked at it  
about 2 years ago). When using unicodepaths you can use '\\?\' as a  
prefix on paths to turn off the conversion I mention above (see  
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/ 
fileio/base/naming_a_file.asp). The fun you can have on windows, I've  
managed to create files that cannot be removed :-)
