[En-Nut-Discussion] nutos conf stdint.h missing

I'm really running out of ideas. GCC claims, that it is searching for
include files in


Checking this directory with

dir c:\winavr-20100110\lib\gcc\..\..\avr\include

shows, that

10.01.2010  02:03            16.556 stdint.h

exists. But during compilation it reports

C:/ethernut-5.1/nut/include/sys/atom.h:106:20: stdint.h: No such file

How can this happen?

While trying to solve problems, it is always the best idea to go with
minimized demos. So let's try without Nut/OS. Create a temporary
directory, e.g. c:\tmp\gcctest.

Create a text file named main.c in this directory with the following

#include <stdint.h>
int main(void) {
  return 0;

Open a command line window, set your path with

set PATH=winavr-20100110\bin;winavr-20100110\utils\bin;%PATH%

and run

avr-gcc main.c

Is the error still there? Or does it compile now, creating a.out?

Btw. is you PC special in any way? Exotic file system, OS-version etc.?
