multilib and using C++ in post-stage1
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
AssignedTo: unassig...@gcc.gnu.org

Output of 'gmake bootstrap' (single job)
Bootstrapping gcc-4.7.0-RC-20120314 on powerpc-ibm-aix7.1.0.0 fails because of
32bit gcc/xgcc cannot load a 64bit libstdc++.a.
It works when I do configure with --disable-build-poststage1-with-cxx
Prerequisites:
Installed binary:
gcc-4.6.2 in /opt/freeware/ from perzl.org,
Self-built:
gmp-5.0.1, configured with ABI=32
mpfr-3.0.0,
mpc-0.8.2,
Toplevel configured with --enable-languages=c,c++
'gmake bootstrap' with single job
The last lines in the output of 'gmake bootstrap' (from attached
bootstrap.out.bz2):
