Well, it's the Python installer that's doing the installing; I assume
it's doing it correctly. In fact, when I look at C:\Windows\SysWOW64, I
can see python27.dll.

So, if I "cd" to "/c/Windows/System32", and do "ls -l python27.dll",
it's really looking at "/c/Windows/SysWOW64" instead? That's why I see
it with msys's "ls" and "file", but not with cmd.exe and "dir", or
depends.exe?

Looks like it's in C:\Windows\SysWOW64\, as it should be.
Thanks, Tim.
