Patch: re-delete gengtype-yacc.y
- From: Tom Tromey <tromey at redhat dot com>
- To: Gcc Patch List <gcc-patches at gcc dot gnu dot org>
- Date: Wed, 10 Oct 2007 08:19:56 -0600
- Subject: Patch: re-delete gengtype-yacc.y
- Reply-to: Tom Tromey <tromey at redhat dot com>
gengtype-yacc.y was removed a while back:
2007-03-26 Zack Weinberg <zackw@panix.com>
* gengtype-parse.c: New file.
* gengtype-yacc.y: Delete.
[...]
... but then apparently resurrected during the switch to GPLv3.
As there are no references to this file in Makefile.in, I think it
should be removed again.
I'm building with the obvious change. Ok if it builds?

* gengtype-yacc.y: Removed.
