      (R7RS_SOURCES): New variable.
      (NOCOMP_SOURCES): Add ice-9/r7rs-libraries.scm.
    
    * module/ice-9/boot-9.scm: Include r7rs-libraries.scm.

      full-unicode, and ratios.  Add TODO comments.
      (%cond-expand): New procedure, derived from code in 'cond-expand'.
      (cond-expand): Reimplement in terms of '%cond-expand'.
    
    * module/ice-9/r7rs-libraries.scm:
      module/scheme/base.scm:
      module/scheme/case-lambda.scm:
      module/scheme/char.scm:

commit 2e1bc2b9c955660c7aad24d839f1f43f32070d58
Author: Mark H Weaver <address@hidden>
Date:   Sun Jan 12 04:47:19 2014 -0500

    Compiler: Support cyclic literal data.
    
    * libguile/vm-i-scheme.c (array-contents): New VM instruction.
    
    * module/language/glil/compile-assembly.scm (vhash-fold-right3,
      fold3, fold2-3): New procedures.
      (add-to-store): Accept new argument 'ancestors'.  Use it to prevent
      infinite loops.  Augment it when traversing into lists, pairs,
      vectors, or arrays.
      (build-constant-store): Adapt to new argument to 'add-to-store'.
      (ref-or-dump): Accept new arguments 'post' and 'f'.  If the referenced
      object has not yet been serialized, augment 'post' to add code that will
      mutate it to the correct value after all initializations.
      (dump1): Accept new argument 'post'.  Return a third value: the new
      'post'.  Pass new arguments to 'ref-or-dump'.
      (dump-constants): Adapt to new argument and return value of 'dump1'.
      Apply post-procs to mutate fields of constants as needed to handle
      cyclic data.

      (scm_read): Call 'scm_resolve_datum_labels'.

      'datum_label_tag'.
