Well here is a case where you may want one huge user datastructure that
can cover many gigabytes - so you would like to have 64bit to adress
this creature. So see the pattern here. One blob in
the c-code custom space that is huge and all guile sitting on a small iland
that could have been 32 bit. So one should be able to compress.
Mayby I'm ignorant on the meaning of compiling to 32bit though.
