| In my msys sytem (perhaps in the msys in Japanese windows),

| mkdir C:/DOCUME~1/Tatsu/LOCALS~1/Temp\\oct-2

| is able to work.
| 
| I think that the former is better as patch.

modified.

| Please give me advises.
| 
| 
| In my speculation, the above prblem is Japanese windows specific problem.
| Please see the following in the prevous threads
| ****************** 
| In Japanese windows, we use Chinese and Japanese charactors (Kanji 
charactors). 
| Japanese windows have the shift-jis kanji code. 
| 
| A shift-jis kanji code consist of 2 bytes.  The first byte code is larger 
than 80(HEX). 
| But second byte is not always larger than 80(HEX) and some kanji uses 
5C(HEX). 
| The 5C(HEX) is the code of '\'. 
| The facts make Jananese kanji code treatment very complex. 
| 
| I do not know the trouble comes from the above. 
| But the treatment of the seperator may be complex for Japanese system. 
| 
| The above is only speculation. 
| That's why I don't have english windows. 
| ********************* 
| 
| I think this is a good chance to kick out this problem.

I don't know how to solve this problem, and I don't think I can accept
a patch that changes the default directory separator character for
Windows to be a forward slash "/" character.
