They are not there, unless I am in the wrong folder. I searched in
c:\windows\winsxs.

I have looked there, that is where I got the redist exe file which did
not work. I then went and got a copy of the file right from Microsoft,
but no luck there either.

I cannot distribute them. So you are saying to compile without the
dll, then run the redist file? I would much rather package everything
as this is meant to be a stand-alone app, runable from anywhere (even
a thumb drive on a computer on which you are a guest, like a hotel or
library machine). It is not meant to install anything or copy any
files, just run in memory and then close when the user decides to
close.

Maybe this is a stupid question. I don't know, I don't use windows.
But what's so special about msvcr and visual studio compiler? Python
compiles fine with gcc under unixes, so is it a problem to compile
python interpreter with mingw and get rid of the proprietary runtime
dependecies? Or does the windows python port make heavy use of ms'
libs?

MinGW uses an older version of Microsoft's runtime MSVCRT.DLL. While
MSVCRT.DLL is present in all commonly used versions of Windows, the
particular version varies and, unless you have licensed an older version
of Visual C++, you probably do not have the right to redistribute it.
