+/* Aug 1, 2003
+ * New *scanf implementation with lots of bug fixes and *wscanf support.
+ * Also now optionally supports hexadecimal float notation, positional
+ * args, and glibc locale-specific digit grouping. Should now be
+ * standards compliant.
+ *
+ * Aug 18, 2003
+ * Bug fix: scanf %lc,%ls,%l[ would always set mb_fail on eof or error,
+ * even when just starting a new mb char.
+ * Bug fix: wscanf would incorrectly unget in certain situations.
+ *
+ * Sep 5, 2003
+ * Bug fix: store flag wasn't respected if no positional args.
+ * Implement vs{n}scanf for the non-buffered stdio no-wchar case.
+ *
+ * Sep 13, 2003
+ * Bug fix: Fix a problem reported by Atsushi Nemoto <anemo@mba.ocn.ne.jp>
+ * for environments where long and long long are the same.
+ *
+ * Sep 21, 2003
+ * Ugh... EOF handling by scanf was completely broken. :-( Regretably,
+ * I got my mind fixed in one mode and didn't comply with the standards.
+ * Things should be fixed now, but comparision testing is difficult when
+ * glibc's scanf is broken and they stubbornly refuse to even acknowledge
+ * that it is... even when confronted by specific examples from the C99
+ * standards and from an official C standard defect report.
