```Hello,

still it doesn't work. I added all values given by avr-cpp -Wp,-v to my PATH Enviroment Variable. Still the compiler is missing stdint.h. For a test I copied the stdint.h from C:\WinAVR-20100110\avr\include to C:\ethernut-5.1\nut\include. I could compile now, but get warnings:

C:/ethernut-5.1/nut/include/stdint.h:121: warning: redefinition of `int8_t'
/WinAVR/avr/include/inttypes.h:67: warning: `int8_t' previously declared here
C:/ethernut-5.1/nut/include/stdint.h:122: warning: redefinition of `uint8_t'
/WinAVR/avr/include/inttypes.h:72: warning: `uint8_t' previously declared here
C:/ethernut-5.1/nut/include/stdint.h:123: warning: redefinition of `int16_t'

The size of the hex file is only 1kb, and only filled with :00000001FF

I have an older Ethernut 1.3 Project from 2004, that is compiling without any hassle. But I have the Ethernut 2.1c Hardware, and need that project working with the changed NIC from 1.3 to 2.1. Maybe I should think about ordering a older hardware.
