GDB head fails to compile for target=arm-elf

[Janne Hellsten]

Hi again,

I went and tried to compile the head CVS revision of GDB.  Alas, it
appears that it doesn't compile on my system (Debian testing).

I configured like so:

src/  -- CVS dir
build-gdb/

In build-gdb dir, I did "../src/configure --prefix=/home/janne/gdb-CVS
--target=arm-elf".  This works well.  However, "make" fails:

</snip>

I wonder what's going on..  Where does the error come from?  I only
see warnings here.

I'm using gcc 3.3.5:

janne@nurbian:~/code/build-gdb$ gcc -v
