I'm assuming you are using the http://student.agh.edu.pl/~mkucia/wiki/doku.php?id=avrada (Do you have other reference?). If so, I do not get this message. Did you run the gen using 
main.exe ATmega328P.xml > atmega328p.ads? 

The xml you can get from AS5. 
Still I do not get any error message at this point.

I don't think you need to modify the xml. But the ads it generated came with with several redundancies, so it did not compile. Have to take them out. So it looks more practical to generate the ads by hand, without the xml, so you can put just what you want to use.

I did not use this. Is this included on GNAT-AVR library? 
Actually you can use the CRT from WinAVR installation, at avr\lib\avr5\crtm328p.o (rename it to crtm328p._o).
