      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'.

commit 38f1bd72dd7d1647405dc3010408eb8c6387265a
Author: Mark H Weaver <address@hidden>
Date:   Sun Jan 12 04:42:18 2014 -0500

    Implement R7RS 'include-ci', and multiple arguments for 'include'.
    
    Relative filenames are now interpreted based on the path of the file
    that contains the filename string, instead of the file that contains
    the include form.
    
    * module/ice-9/psyntax.scm (%read-files-for-include): New procedure.
      (include): Support multiple filename arguments.  Reimplement in terms
      of '%read-files-for-include'.
      (include-ci): New macro.
    
    * module/ice-9/psyntax-pp.scm: Regenerate.
    
    * doc/ref/api-evaluation.texi (Local Inclusion): Update docs.

commit db2874fe6218f859bb64c8fa258cde5d7a0cabf8
Author: Mark H Weaver <address@hidden>
Date:   Sun Feb 2 02:32:15 2014 -0500

    Implement 'set-port-read-option!'.
    
    * libguile/read.c (scm_keyword_prefix, scm_keyword_postfix):
      Rename to 'sym_prefix' and 'sym_postfix'.
      (scm_copy, scm_positions, scm_case_insensitive, sym_keywords,
      sym_r6rs_hex_escapes, sym_square_brackets, sym_hungry_eol_escapes,
      sym_curly_infix, sym_inherit): New variables.
      (scm_set_port_read_option_x): New procedure.
      (init_read_options): Adapt to the renamed 'sym_prefix' and
      'sym_postfix' variables.
    
    * libguile/read.h (scm_set_port_read_option_x): New prototype.
    
    * doc/ref/api-evaluation.texi (Scheme Read): Add docs.

commit 10421c4f7ed8259aacb850c25ad44898fd8f9f83
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.

      resolve_datum_labels, scm_resolve_datum_labels): New static functions.
      (scm_read_array): Handle datum labels.
      (scm_read): Call 'scm_resolve_datum_labels'.
      (init_read_context): Initialize 'datum_label_table', and
      'datum_label_tag'.
    
    * module/srfi/srfi-38.scm (read-with-shared-structure): Make this an
      alias for Guile's core 'read'.  Remove the old implementation.
