Bug #4712: File.writable? inaccurate in windows

Hello. Here's what happens (when a user doesn't have admin privileges in windows 7):

c:\Program Files (x86)\NetBeans 6.9.1>irb --simple-prompt
>> File.writable?('.')
=> true
>> File.writable?('./uninstall.exe')
=> true
>> File.open('./uninstall.exe', 'wb')
Errno::EACCES: Permission denied - ./uninstall.exe
        from (irb):4:in `initialize'
        from (irb):4:in `open'
        from (irb):4

So I think writable was returning true in error here.
Cheers!
