From 554fd8c5195424bdbcabf5de30fdc183aba391bd Mon Sep 17 00:00:00 2001 From: upstream source tree Date: Sun, 15 Mar 2015 20:14:05 -0400 Subject: obtained gcc-4.6.4.tar.bz2 from upstream website; verified gcc-4.6.4.tar.bz2.sig; imported gcc-4.6.4 source tree from verified upstream tarball. downloading a git-generated archive based on the 'upstream' tag should provide you with a source tree that is binary identical to the one extracted from the above tarball. if you have obtained the source via the command 'git clone', however, do note that line-endings of files in your working directory might differ from line-endings of the respective files in the upstream repository. --- libjava/gnu/java/lang/natMainThread.cc | 65 ++++++++++++++++++++++++++++++++++ 1 file changed, 65 insertions(+) create mode 100644 libjava/gnu/java/lang/natMainThread.cc (limited to 'libjava/gnu/java/lang/natMainThread.cc') diff --git a/libjava/gnu/java/lang/natMainThread.cc b/libjava/gnu/java/lang/natMainThread.cc new file mode 100644 index 000000000..5cba24700 --- /dev/null +++ b/libjava/gnu/java/lang/natMainThread.cc @@ -0,0 +1,65 @@ +// natMainThread.cc - Implementation of MainThread native methods. + +/* Copyright (C) 1998, 1999, 2000, 2001, 2003, 2006 Free Software Foundation + + This file is part of libgcj. + +This software is copyrighted work licensed under the terms of the +Libgcj License.
