* module/ice-9/boot-9.scm (find-versioned-module): Remove. Still had some bugs (e.g. for "." in the path and in finding compiled files), did too much computation and statting, and we don't really want to promote versioning. Nor do we want to hard-code a particular encoding of versions in the file-system. Perhaps the real way to do this is to be extensible somehow. (try-module-autoload): Just dispatch to primitive-load-path in all cases. * module/rnrs * module/rnrs.scm: * module/rnrs/arithmetic/bitwise.scm: * module/rnrs/arithmetic/fixnums.scm: * module/rnrs/arithmetic/flonums.scm: * module/rnrs/base.scm: * module/rnrs/conditions.scm: * module/rnrs/control.scm: * module/rnrs/enums.scm: * module/rnrs/eval.scm: * module/rnrs/exceptions.scm: * module/rnrs/files.scm: * module/rnrs/hashtables.scm: * module/rnrs/io/simple.scm: * module/rnrs/lists.scm: * module/rnrs/mutable-pairs.scm: * module/rnrs/mutable-strings.scm: * module/rnrs/programs.scm: * module/rnrs/r5rs.scm: * module/rnrs/records/inspection.scm: * module/rnrs/records/procedural.scm: * module/rnrs/records/syntactic.scm: * module/rnrs/sorting.scm: * module/rnrs/syntax-case.scm: * module/rnrs/unicode.scm: Move these files, eliding the "6/" infix, so that they are in the normal (unversioned) module path.
