Strictly speaking offsetof cannot be applied to non-PODs. The only thing that makes that class non-POD is the protected attribute, but that does not alter the physical layout. So the compiler is emitting a harmless warning (newer versions have tightened the check to warn when you are using offsetof on a non-base class). My cris-elf builds worked fine, but config-list.mk only builds stage 1, it does not build libgfortran. Can you give me instructions on how to build your target on my x86 workstation? Thanks. Diego.
