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. --- libiberty/rename.c | 36 ++++++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) create mode 100644 libiberty/rename.c (limited to 'libiberty/rename.c') diff --git a/libiberty/rename.c b/libiberty/rename.c new file mode 100644 index 000000000..ad342ffca --- /dev/null +++ b/libiberty/rename.c @@ -0,0 +1,36 @@ +/* rename -- rename a file + This function is in the public domain. */ + +/* + +@deftypefn Supplemental int rename (const char *@var{old}, const char *@var{new}) + +Renames a file from @var{old} to @var{new}.
