Re: patch: global -u on win32 with src root at drive root

[Shigio YAMAGUCHI]

Hi Kai

It seems that there is no problem in acceptance of tag files in system's

Here is a patch for it.
I don't know whether or not this code works in Windows environment.
If you can modify this for Windows, I will accept it. Thanks.
