Yeah, I got those warnings in my sparc and hppa builds, but they are
harmless.  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.
