Complete misunderstanding. The paths given by avr-cpp -Wp,-v are include
paths, not paths to find executables. I only wanted to know what the
output is.

Moving include files around may make things worse. Instead we need to
figure out, that the right compiler version is called and that it uses
the right include paths.

OK, do the following:

* open a command line window.
* cd to the nutbld directory that you created with the Configurator
* add the paths to your compiler, e.g.
 set PATH=C:\WinAVR\bin;C:\WinAVR\utils\bin;%PATH%
* run "avr-gcc --version" and "avr-cpp -Wp,-v"
* post the complete cmds and responses to this list (text via cut and
copy, no screenshot)
* run "make clean all install"
* if that ends with an error, post the error message to this list (not
the full dump, just the 2 or 3 lines containing the first error)

If that sequence fails in between, then post the output up to this point.

The old version used it's own integer types, while we later switched to
stdint.h, because it is standard and nowadays support by most libraries.
In that sense, the newer Nut/OS versions depend a bit more on the
library. But your case is so common, that it must work. It's just a
problem of your two avr-gcc versions installed on your hard disk. This
needs to be sorted out.

I usually have at least 10 different compiler versions installed. With
little care this provides no problems.
