The Squeak3D polygon was updated for 64 bits. It is built and included as
an external plugin on all 32 bit and 64 bit Spur VMs. It builds with only
one (expected) warning:
../../src/plugins/Squeak3D/Squeak3D.c:6:13: warning: unused variable
1 warning generated.
So whatever the issue is is deeper than simply not having been updated.
