Oups, sorry for that. Here is the error message with the latest svn version:

I looked a bit at the source, and the gcc/config/darwin.h declares a
ADJUST_FIELD_ALIGN with two arguments whereas all other back-ends that
declare ADJUST_FIELD_ALIGN have only two arguments. And it seems that
stor-layout.c assumes that if we have ADJUST_FIELD_ALIGN defined, then
we're on darwin.
