----------
-Changes in version 1.49d:
+Changes in version 1.75a:
+* 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 1.49b, 2002-08-12:
+Changes in version 1.75:
+
+* Bison should now work on 64-bit hosts.
+
+* Indonesian translation thanks to Tedi Heriyanto.
+
+* GLR parsers
+ Fix spurious parse errors.
+
+* Pure parsers
+ 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 $$ is untyped, and $1 typed:
+
+ untyped: ... typed;
+
+ but the converse remains an error:
+
+ typed: ... untyped;
+
+* Values of mid-rule actions
+ The following code:
+
+ foo: { ... } { $$ = $1; } ...
+
+ was incorrectly rejected: $1 is defined in the second mid-rule
+ action, and is equal to the $$ of the first mid-rule action.
+
+Changes in version 1.50, 2002-10-04:
* GLR parsing
The declaration
%dprec and %merge on grammar rules allow parse-time resolution of
ambiguities. Contributed by Paul Hilfinger.
+ Unfortunately Bison 1.50 does not work properly on 64-bit hosts
+ like the Alpha, so please stick to 32-bit hosts for now.
+
* Output Directory
When not in Yacc compatibility mode, when the output file was not
specified, running `bison foo/bar.y' created `foo/bar.c'. It
This kludge also addresses some C++ problems when the stack was
extended.
