powerpc/powerpc64 4.4 build issue on etch

[Laurent GUERBY <laurent@guerby.net>]

Hi,

On my etch system I configured trunk as follows:

../trunk/configure --disable-nls --enable-__cxa_atexit
--enable-threads=posix --with-mpfr=/opt/cfarm/mpfr-2.3.2
--enable-languages=c,ada --with-cpu=default32  --disable-softfloat
--enable-targets=powerpc-linux,powerpc64-linux
--prefix=/n/40/guerby/install-trunk-144268 

And the build failed in stage3 with:

<<

Looking around I found out someone with the same error on another
platform:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32193

Also I haven't seen gcc 4.4 powerpc results from debian in February,
last result was in January:
http://gcc.gnu.org/ml/gcc-testresults/2009-01/msg03165.html

I noted this build uses --disable-werror may be it's to workaround the
issue above? On #gcc it was suggested it was more an error in the libc
include than anything else, any idea?

I'm rebuilding with --disable-werror.

Thanks in advance,

Laurent
