------- Comment #15 from howarth at nitro dot med dot uc dot edu 2007-12-16 05:44 ------- The problem was that gcc/config/i386/t-crtpc and gcc/config/i386/t-crtfm had build commands which didn't use MULTILIB_CFLAGS. Now that those are added all of the object files in the x86_64 subdirectory are of the proper architecture.
