Yes.  I've been thinking about this for years, off an on.

EDG's compiler uses arbitrary numbers of host words, and that really
is necessary.  There are 32-bit chips without 64-bit data types, that
need to cross compile to 64-bit chips with 128-bit data types.
Whether we use gmp, or roll a small library of our own, we need this
functionality.
