+  Bug: in initinput(), the call ugchar(EOF) used the ungetcount member
+  of the top Input structure without initializing it. Thanks to Jeff
+  Johnson for finding this, Robert Scheck for reporting it, and Uli
+  Drepper for implementing MALLOC_PERTURB_, a cheap way to find uses of
+  uninitialized memory.
