Please never send e-mail to both gcc-help@xxxxxxxxxxx and gcc@xxxxxxxxxxxx This message is only appropriate for gcc-help@xxxxxxxxxxxx Thanks. The bug is in the way that gcc/gpg++spec.c uses LIBSTDCXX_STATIC, or possibly in the way that macro is defined in gcc/config/rs6000/aix.h. I don't see a simple fix. Please do file a bug, per http://gcc.gnu.org/bugs.html. Thanks. Ian
