RE: copyfile() not working on my new Win7 PC

[Tim Rueth]

Tatsuro-san,

When I executed ...MSYS\bin\sh from my command prompt, it worked fine.  I
then began to suspect that perhaps there was something wrong with my 3.2.3
installation.  So I did a fresh installation (this time installing 3.2.4)
and everything is fine now.  Thanks for your help!
