I think the following discrepancy should probably be fixed:

                             '(bytestructures guile numeric-data-model)))
   $2 = #f

To clarify:

The module (bytestructures guile numeric-data-model) provides the 'lp64' condition via 'cond-expand-provide'.

The 'cond-expand' imported from the (guile) module correctly sees this, but the one imported from (scheme base) seems to ignore it.
