HOST_WIDE_INT should automatically be defined to "long long". If this happens,
then 32b->64b crosses should build. If this does not happen, they will not
build. One of the symptons of this failure is the problem you noted above.
The HOST_WIDE_INT stuff is in hwint.h.
Just taking a wild guess, this might be a problem with Zack's header file
reorganization patches on the bib branch. hwint.h needs MAX_LONG_TYPE_SIZE
from the tm.h file in order to correctly choose the right size for
HOST_WIDE_INT. I do not have a copy of bib, so I can't easily check this.

This may be a side effect of the above problem.
