/home/willy/gcc/gcc-3.4/configure --host=ia64-linux --target=arm-linux
--prefix=/home/willy/arm --enable-languages=c,ada --disable-shared --disable-nls
make

This part works fine.  Then I need to build gnatlib:

cd gcc
make gnatlib

Can you try to compile a native 3.4.0 and then try again the cross compiler?  It might be a native 
compiler miscompiling the cross compiler?

I compiled a native 3.4.2 (CVS as of a day or two ago) for the host compiler.
This works even less well, dying during the 'make' portion of compiling the
cross-compiler:

mkdir -p ada/bldtools
cp -p /home/willy/gcc/gcc-3.4/gcc/ada/sinfo.ads
/home/willy/gcc/gcc-3.4/gcc/ada/nmake.adt
/home/willy/gcc/gcc-3.4/gcc/ada/xnmake.adb ada/bldtools
(cd ada/bldtools; gnatmake -q xnmake ; ./xnmake -b ../nmake.adb )
make[1]: *** [ada/nmake.adb] Error 139

$ gnatmake xnmake 
gnatmake: "xnmake" up to date.
$ ./xnmake -s ../nmake.ads

I double-checked that the gnatlink/gnatmake/gnatbind/gcc in my path are coming
from the new compiler:

You are mixxing two different issues.

The native bootstrap issue on ia64 is already part of another PR.

This one seems to be a GCC error when generating debug info.

Does this work in 4.0.x?
