If there are differences, and requiring (lib "1.ss" "srfi") gets you
procedures that aren't conformant with SRFI 1, that's a big problem.  I
recommend strongly against it.  (It seems changing the "list.ss" import
wouldn't be that much of a problem.)  I generally recommend importing
only specific procedures from SRFI 1, given its size and the genericness
of its names.
