Thanks for trying it and for sending me the (voluminous) log.

I doubt whether it's worth your time or mine to debug this, so I
propose that we officially discontinue support for building Bison with
K&R C.  Here is a proposed (and untested patch) for discussion; if
there's no disagreement, I'll test and install it.

        * NEWS: Officially drop support for building Bison with K&R C,
        since it didn't work anyway and it's not worth worrying about.
        * Makefile.maint (wget_files): Remove ansi2knr.c.
        (ansi2knr.c-url_prefix): Remove.
        * .cvsignore: Remove ansi2knr, ansi2knr.*.
        * lib/Makefile.am (AUTOMAKE_OPTIONS): Remove.
        * src/Makefile.am (AUTOMAKE_OPTIONS): Remove.

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