When testing a 64 bits compiler ACATS is clean but gnat.dg has one FAIL:

http://gcc.gnu.org/ml/gcc-testresults/2009-02/msg02180.html

FAIL: gnat.dg/pack3.adb execution test
raised PROGRAM_ERROR : pack3.adb:29 explicit raise

pack3.adb test was introduced together with this patch:

2008-03-07  Eric Botcazou  <ebotcazou@adacore.com>

        * decl.c (gnat_to_gnu_entity) <E_Modular_Integer_Subtype>: Add
        comment for the packed array type case.
        * utils.c (build_template): Use a loop to strip padding or
        containing records for justified modular types.

To build on powerpc64 on debian etch one small patch is needed:

Index: configure
===================================================================

 # in both places for now and restore CFLAGS at the end of config.

-fi

 # Find other programs we need.
 if test -n "$ac_tool_prefix"; then

Otherwise the build showing this FAIL is still available on compile farm gcc40
in /n/40/guerby/build-144347 and installed in
/n/40/guerby/install-trunk-144347/bin . Configure:

export CC="gcc -m64"
../trunk/configure --disable-nls --enable-__cxa_atexit --enable-threads=posix
--with-mpfr=/opt/cfarm/mpfr-2.3.2-64 --enable-languages=c,ada
--prefix=/n/40/guerby/install-trunk-144347 --with-long-double-128
--with-gmp=/opt/cfarm/gmp-4.2.4-64/

ssh public key can be added on request to my account (8h30 for bootstrap+check
c,ada on gcc40).
