Hi Marc;

  Thanks for your help.

  First tried the following:

../gdb-6.0/configure \
--host=i686-unknown-linux-gnu \
--build=i686-unknown-linux-gnu \
--target=arm-arm9-linux-gnu

But this failed due to the fact that my native gcc and friends are simplly 
named "gcc", not "i686-unknown-linux-gnu"...

then I tried:

../gdb-6.0/configure --target=arm-arm9-linux-gnu

which seemed to work fine for a native gdb which (hopefully) understands arm9 
corefiles, a crossgdb...

Then I tried:

../gdb-6.0/configure \
--host=arm-arm9-linux-gnu \
--build=i686-unknown-linux-gnu \
--target=arm-arm9-linux-gnu

because I want a native arm9 gdb they can run on the board itself.

This failed due to:

I don't have an arm-arm9-linux-gnu-ar executeable as a result of running 
crosstool :-(

So, I guess I will try to get a cross compiler built via LSF (Linux From 
Scratch at http://www.fr.linuxfromscratch.org/view/lfs-4.1/index.html) and 
look further into crosstool scripts...
