This is still not enough info.
I bet a beer at the GCC summit, it is trying to invoke gcc instead of avr-gcc
for avr-gnatmake.

I'm unable to build even a C compiler to the avr target, binutils-2.16.1 +
newlib-1.13.0 + gcc-4.1.1-prerelease I get:

In my recollection, cross gnatmake were properly calling TARGET-gcc, ie:

Bernd what version of various items in the toolchain did you use? Did you apply

This bug is target independent. 
I see the same behaviour for --target=mingw32.

I just build a mingw32 cross with c,ada from 4.1.1 prerelease (using native
Linux c,ada GCC 4.1.0 as base compiler) and it invokes properly ming32-gcc:

$ mingw32-gnatmake -Pp -v

So this is probably something very specific to your setup. I'm setting the PR
in WAITING state since I cannot confirm it without some additional information.

------- Comment #10 from laurent at guerby dot net  2006-05-27 17:09 -------
Oops sorry, didn't see that my log show the problem you mentionned (and not the
one I imagined), the library building tools of gnatmake when using a project
file are indeed looking for and using native tools (it "succeeds" on my machine
because I have the native compiler in PATH).

I wrote a patch
http://gcc.gnu.org/ml/gcc-patches/2006-05/msg01411.html

It seems to fix the problem:

found /mnt/data-5-1/guerby/install/bin/mingw32-gcc
found /mnt/data-5-1/guerby/install/bin/mingw32-ar
found /mnt/data-5-1/guerby/install/bin/mingw32-ranlib

Bernd, could you contribute (attach here) your Makefile and ada RTS changes so
that Ada build with AVR target succeeds? I see lots of ICE due to the target
8bit-ness while building the Ada RTS so I assume you cut it or disable it
somehow.

Thanks in advance,

Laurent

Since I don't like to have mutiple copies of the same thing around, I'd
rather provide only a link into AVR-Ada repo.:
