--- Comment #66 from Jonathan Wakely <redi at gcc dot gnu.org> --- Yes, I was afraid the RTEMS failures might be a different problem. Are the symptoms the same? i.e. missing C++ standard library headers? Comment 17 suggests you're seeing missing libgcc headers, which is created by a different makefile. Maybe a similar kluge is needed in libgcc/Makefile for build=*darwin* What are your build, host and target triplets?
