If anyone really cares, the problem is that the SunOS 4.0.3 version of
<sundev/cg6reg.h> defines some mmap offsets in terms of NBPG (the page
size of the machine you're compiling on (more or less)), which is bad
because the SS-1 has a different page size than Sun-3s and other Sun-4s
(4K instead of 8K).  The 4.0.3c and 4.1 versions of this include file
correctly define the mmap offsets, which are the same on all systems.
