Hi,
it has worked this time. Here is what I did:

I installed the gcc and gnat 3.1 packages from Matthias on Intel. I made then 
symbolic links from gcc-3.1 to gcc and from gnatbind-3.15 to gnatbind and 
similar for the other gnat tools.

I installed a s390 glibc in /usr/local and built and installed cross-binutils 
and cross-gcc and cross-ada using the latest source tarballs by issueing:

../binutils/configure --target=s390-ibm-linux 

make
make install

./gcc/configure --target=s390-ibm-linux --enable-languages="c,ada" 

make

cd gcc
make gnatlib 
make cross-gnattools

cd ..
make install

I built the native gcc and ada compiler on Intel by issueing:

../gcc/configure --prefix=/home/ton/usr/ --host=s390-ibm-linux 
--build=i386-pc-linux-gnu --enable-languages="c,ada"

make

cd gcc
make cross-gnattools

I installed the compiler then in my home directory using

cd ..
make install

and made a tarball from the installed files. I copied also the library files
/usr/local/lib/gcc-lib/s390-ibm-linux/3.1/adalib and
/usr/local/lib/gcc-lib/s390-ibm-linux/3.1/adainclude
from the crosscompile step to the tarball. The tarball was then transferred 
to the target system and finally the ada bootstrap made according to

http://gcc.gnu.org/install/build.html

using the previously built compiler.


Please be sure, that the configure step says something like below. If not, 
the make will work, but does some strange things.

checking for s390-ibm-linux-gnatbind... s390-ibm-linux-gnatbind
checking for compiler driver that understands Ada... s390-ibm-linux-gcc



Regards,
Gerhard
