From d6f9dbc493df725d3d574403549de142c5e1222a Mon Sep 17 00:00:00 2001 From: Kenneth Russel Date: Mon, 24 Oct 2005 19:21:03 +0000 Subject: Merged JSR-231 branch on to the main JOGL trunk. The main trunk now contains the evolving JSR-231 Reference Implementation and the JSR-231 branch is permanently closed. git-svn-id: file:///usr/local/projects/SUN/JOGL/git-svn/svn-server-sync/jogl/trunk@401 232f8b59-042b-4e1e-8c03-345bb8c30851 --- src/net/java/games/gluegen/cgram/GnuCParser.g | 864 -------------------------- 1 file changed, 864 deletions(-) delete mode 100644 src/net/java/games/gluegen/cgram/GnuCParser.g (limited to 'src/net/java/games/gluegen/cgram/GnuCParser.g') diff --git a/src/net/java/games/gluegen/cgram/GnuCParser.g b/src/net/java/games/gluegen/cgram/GnuCParser.g deleted file mode 100644 index feed4518e..000000000 --- a/src/net/java/games/gluegen/cgram/GnuCParser.g +++ /dev/null @@ -1,864 +0,0 @@ -/*%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% - - Copyright (c) Non, Inc. 1998 -- All Rights Reserved - -PROJECT: C Compiler -MODULE: GnuCParser -FILE: GnuCParser.g - -AUTHOR: Monty Zukowski (jamz@cdsnet.net) April 28, 1998 - -DESCRIPTION: - This is a grammar for the GNU C compiler.
