+ * or subdirectory has been added to the directory. (This causes
+ * run-test.sh to fail, for instance.) GetFileAttributesEx() is
+ * better, it returns the updated timestamp right away.
+ *
+ * 2) stat() does some strange things related to backward
+ * compatibility with the local time timestamps on FAT volumes and
+ * daylight saving time. This causes problems after the switches
+ * to/from daylight saving time. See
+ * http://bugzilla.gnome.org/show_bug.cgi?id=154968 , especially
+ * comment #30, and http://www.codeproject.com/datetime/dstbugs.asp .
+ * We don't need any of that, FAT and Win9x are as good as dead. So
