 Thanks a lot for doing that experiment.  Please, could you diff the .i
 files from the in-tree compiler and stock one from the pkgsrc?  The
 interesting files are rs6000.i, and maybe function.i and explow.i.  rm
 the .o file, run make, copy the command and re-run with -save-temps
 added.  Hopefully, that should point out which macros we've got wrong.
