read at least 1 byte from the input file without problems. This
fixes a bug in uncompress(1) that causes the accidental removal
of files that happen to have the same name as the output file,
even when the uncompression fails and is aborted, i.e.:
$ echo hello world > hello
$ touch hello.Z
$ ls -l hello*
-rw-rw-r-- 1 giorgos giorgos 12 Jun 14 13:33 hello
-rw-rw-r-- 1 giorgos giorgos 0 Jun 14 13:33 hello.Z
$ ./uncompress -f hello
uncompress: hello.Z: Inappropriate file type or format
$ ls -l hello*
-rw-rw-r-- 1 giorgos giorgos 0 Jun 14 13:33 hello.Z

of the recent WARNS commits. The idea is:
1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.
compress uses setfile() to make flags, ownership and mode of the output
the same as those of the original. However, if the filesystem holding the
output file doesn't support these operations, compress prints a warning.
This bites a bit with NFS directories, which always fail the chflags()
operation. If the file system doesn't support the operation, then the
flags data wasn't valid on the original file anyway, so the warning is
spurious.
