gcc_update revision 1.1.1.3
1 #! /bin/sh 2 # 3 # Update a local Subversion, Git or Mercurial tree from the GCC 4 # repository, with an emphasis on treating generated files correctly, so 5 # that autoconf, gperf et al are not required for the ``end'' user. 6 # 7 # (C) 1998, 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2009, 2010, 8 # 2011 Free Software Foundation 9 # Originally by Gerald Pfeifer <pfeifer (at] dbai.tuwien.ac.at>, August 1998. 10 # 11 # This script is Free Software, and it can be copied, distributed and 12 # modified as defined in the GNU General Public License.
