The portable dumper changes have completely hosed mswindows, I think its something to do with the opaque_ptr changes. mswindows uses these to store menu item ids in a hash table. It looks like that emacs is unable to get the items out of the hash table. The following patch fixes things although I do not understand the code enough to know whether this is the correct patch. I'll apply this tomorrow unless someone comes up with a correct patch. andy 1999-08-31 Andy Piper <andy(a)xemacs.org&gt; * opaque.c (equal_opaque_ptr): define.
