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/include/posix.h | 207 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 207 insertions(+) create mode 100644 libjava/include/posix.h (limited to 'libjava/include/posix.h') diff --git a/libjava/include/posix.h b/libjava/include/posix.h new file mode 100644 index 000000000..c49da05eb --- /dev/null +++ b/libjava/include/posix.h @@ -0,0 +1,207 @@ +// posix.h -- Helper functions for POSIX-flavored OSs. + +/* Copyright (C) 2000, 2002, 2003, 2006, 2010 Free Software Foundation + + This file is part of libgcj. + +This software is copyrighted work licensed under the terms of the +Libgcj License.
