Yes. Actually there are more files, but I wanted to start with these
simple ones first.

The directory structure is

C:\ethernut-4.9.6
  nut <- Source tree
    fs <- nutlibfs sources
    .... <- other sources

Generally we use
http://www.yagarto.de/
for building arm-elf binaries on Windows. YAGARTO is build with mingw.
However, the Ethernut developers do not need to install cygwin or mingw.
So far all binaries run on a native Windows command shell.

I'll try to do this tommorrow.

I'll try this as well.

One reason for looking at CMake as an alternative to GNU autotools is,
that we do not want to force Windows users to install Cygwin or force OS
X users to install fink. It'd be great if CMake can help here.

Many thanks so far for your prompt reply,
