win32utils devel - Sep 2007 - Pass by reference bug in win32/api?

I spotted this as the result of the latest win32-file-stat tests I''ve 
been running:

require ''windows/path''
include Windows::Path

file1 = ''test''
file2 = file1.dup

PathStripToRoot(file1)

p file1 => "\000est"
p file1 => "\000est"

Win32API (stdlib) doesn''t do this. Is this our fault?

Regards,

Dan
