>Description:
Both gzip & gunzip fail to preserve the input file's times on files with
the immutable and/or append flags because chflags() is called before utimes().
 
>How-To-Repeat:
$ /usr/bin/touch /tmp/foo
$ /bin/chflags uchg /tmp/foo
$ /usr/bin/gzip -v /tmp/foo
gzip: couldn't utimes: /tmp/foo.gz: Operation not permitted
/tmp/foo: -99.9% -- replaced with /tmp/foo.gz
>Fix:
I sent a simple patch to FreeBSD, making it run utimes() / chflags()

Note that src/usr.bin/compress/compress.c does the right thing...
