(libgcj-$(gcc_version).jar): Use $(JAR). (src.zip): Likewise. * configure: Rebuilt. * configure.ac: Check for jar. Removed code to set ZIP. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@112654 138bc75d-0d04-0410-961f-82ee72b054a4 --- fastjar/shift.c | 166 -------------------------------------------------------- 1 file changed, 166 deletions(-) delete mode 100644 fastjar/shift.c (limited to 'fastjar/shift.c') diff --git a/fastjar/shift.c b/fastjar/shift.c deleted file mode 100644 index 2b08a2efab2..00000000000 --- a/fastjar/shift.c +++ /dev/null @@ -1,166 +0,0 @@ -/* shift.c -- utilities to move regions of data in a file. - Copyright (C) 2004, 2005 Free Software Foundation, Inc. - -This program is free software; you can redistribute it and/or modify -it under the terms of the GNU General Public License as published by -the Free Software Foundation; either version 2 of the License, or (at -your option) any later version. - -This program is distributed in the hope that it will be useful, but -WITHOUT ANY WARRANTY; without even the implied warranty of -MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
