AFAICT the m68k was the last target needing twiddling to avoid
unexpected failures on vrp47.c (from reading comments in the bz).
The m68k (like others already mentioned) breaks the conditionals down
rather than combining them into a logical with single compare/test.
Fixed in the obvious way and installed on the trunk.
