Subject: (main): Flush stdout before switching to unbuffered mode
X-Git-Tag: FILEUTILS-4_0l~59
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=93c2c18a801768ddf5d124b303b7d3d1c5a76001;p=thirdparty%2Fcoreutils.git

(main): Flush stdout before switching to unbuffered mode
and calling tail_forever.  Required only on Solaris2.7 -- on other
systems, using setvbuf to switch to unbufferd mode does the flush.
