+3RD PARTY BUGS:
+
+ * redhat (v?) graphical install bomb-out?
+
+ * GNU diff 2.7: diff -rN does not see a new directory with empty file
+
+ * GNU patch 2.1: <must find simple example> if patch chokes on a
+ hunk, or on allegedly unsorted hunks in a diff, it may stop
+ without a trace of failure (create .rej file, print error or
+ dump core) and just ignore any further diffs.
+
+ * glibc 2.0:
+
+ f = fopen ("/dev/null", "r")
+ assert (feof (f))
