+       gnulib: improve prefixing.
+       * configure.ac (gl_PREFIXED_LIBOBJS): Don't rename it, rather,
+       change the value of...
+       (gl_LIBOBJS): this.
+       Adjust more variables.
+       * etc/prefix-gnulib-mk (prefix_assignment): Don't rename
+       gl_LIBOBJS.
+       (prefix): Also transform rules whose targets have slashes.
+       Use $prefix liberally.
+       Map @MKDIR_P@ to $(MKDIR_P).
+       Prefix directories that are mkdir'd.

+
+       build: fix paths.
+       When using $(top_builddir) inconsistently, Make (including GNU
+       Make) is sometimes confused.  As a result it may want to build
+       lib/libbison.la and $(top_builddir)/lib/libbison.la (the same
+       file, different names) concurrently, which, amusingly enough,
+       might end with:
+
+         ranlib lib/libbison.a
+         ranlib lib/libbison.a
+         make[2]: *** [lib/libbison.a] Segmentation fault
+
+       on OS X.
+
+       * doc/local.mk, src/local.mk: Do not use $(top_builddir) when not
+       needed.

+
+       distcheck: fix.
+
+        * examples/calc++/Makefile.am: (EXTRA_DIST): Ship calc.stamp.

+
+       * tests/local.mk (TESTSUITE_AT): Add named-refs.at.

+
+       Miscellaneous code readability improvements.
+
+       * src/reader.c (reader): Move %define front-end variable
+       defaults and checking into...
+       (prepare_percent_define_front_end_variables): ... this new
+       function.
+
+       * src/scan-gram.l (INITIAL): For consistency with string
+       literals, don't store open quote on character literal.  It's
+       discarded before returning anyway.
+       (SC_ESCAPED_CHARACTER): Similarly, don't store close quote.
+       Make length test more readable, and make the character stored
+       for an empty literal more obvious while consistent with the
+       previous behavior.
+
+       * src/symtab.c, src/symtab.h: Rename USER_NUMBER_ALIAS to
+       USER_NUMBER_HAS_STRING_ALIAS throughout.
+       * src/symtab.c (symbol_make_alias): Remove comment from symtab.c
+       that is repeated in symtab.h.  Improve argument names to make it
+       clear which side of the symbol-string alias pair is which.
+       (symbol_check_alias_consistency): Improve local variable names
+       for the same purpose.
+       * src/symtab.h (struct symbol): Make comments about aliases
+       clearer.
+       (symbol_make_alias): Improve comments and argument name.
+       * src/output.c (token_definitions_output): Update for rename to
+       USER_NUMBER_HAS_STRING_ALIAS and improve comments about aliases.
