Subject: Include posixver.h.
X-Git-Tag: TEXTUTILS-2_0_21~71
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=1183723f2565d3aa1918de2e1ce41322db3076d4;p=thirdparty%2Fcoreutils.git

Include posixver.h.
(usage): Document only the intersection of the old and new behaviors,
to encourage portability.
(main): Revert to previous behavior, except report
an error and exit if the obsolete syntax is used and if conforming
to the new standard.
