+* Bison can no longer be built by a K&R C compiler; it requires C89 or
+  later to be built.  This change originally took place a few versions
+  ago, but nobody noticed until we recently asked someone to try
+  building Bison with a K&R C compiler.

+Changes in version 1.75:
 
 * Bison should now work on 64-bit hosts.

   Some people redefine yyerror to steal yyparse' private variables.
   Reenable this trick until an official feature replaces it.
 
+* Type Clashes
+  In agreement with POSIX and with other Yaccs, leaving a default
+  action is valid when $$ is untyped, and $1 typed:
+
+       untyped: ... typed;

+  but the converse remains an error:
+

+
+  was incorrectly rejected: $1 is defined in the second mid-rule
+  action, and is equal to the $$ of the first mid-rule action.
