+
+ * cpplib.h (TTYPE_TABLE): Rearrange to use only two per-entry
+ macros, not five.
+
+ * cpphash.h (TOKEN_NAME): New macro.
+ (_cpp_spell_operator): Deleted.
+ (token_spellings): Now _cpp_token_spellings.
+
+ * cppexp.c: Use TOKEN_NAME or TYPE_NAME, not _cpp_spell_operator.
+ * cpplex.c: Use OP and TK macros when expanding the
+ TTYPE_TABLE. Eliminate token_names. For non-OPERATOR tokens,
+ store the stringification of the enumeration name (CPP_CHAR,
+ etc.) in the name slot of token_spellings.
+ Use TOKEN_NAME and/or TOKEN_SPELL, do not reference
+ token_spellings directly.
+ * cpplib.c: Use TOKEN_SPELL.
+
+ * cpplex.c (_cpp_push_token): If the token being pushed back
+ is the previous token in this context, just subtract one from
+ context->posn.
+ * cppmacro.c (save_expansion): Clear aux field when storing a
+ placemarker.
+
2000-07-18 Jakub Jelinek <jakub@redhat.com>
* cpplex.c (cpp_scan_buffer): Output line command even at the stop
