+       build: avoid warnings about set-but-not-used variables
+       * lib/bitset_stats.c (bitset_stats_list): Remove declaration
+       and set of unused local, "type".
+       * lib/ebitset.c (ebitset_init): Likewise, for "size".
+       * lib/lbitset.c (lbitset_not): Likewise, for "elt".

+
+       lalr1.cc: remove trailing comma from enumerator list.
+       * data/lalr1.cc (yy::parser): Here.  This suppresses a -pedantic
+       warning.

+
+       tests: add -pedantic for --enable-gcc-warnings.
+       This should help to avoid some portability problems.  For example,
+       it would have revealed the empty unions fixed by the last patch
+       * configure.ac (WARN_CFLAGS_TESTS, WARN_CXXFLAGS_TEST): Implement.
+       * tests/synclines.at (AT_TEST_SYNCLINE): Avoid -pedantic warning
+       about an empty translation unit.
