Subject: [HAVE_ST_BLOCKS || _POSIX_VERSION]: Add extern dcl
X-Git-Tag: TEXTUTILS-1_14d~56
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=347c2d6d3039e9a2df6ab033e1d268d8b096ba83;p=thirdparty%2Fcoreutils.git

[HAVE_ST_BLOCKS || _POSIX_VERSION]: Add extern dcl
of unused variable so that after preprocessing, the file will never
be empty.  Otherwise, some compilers in ANSI mode (among them, the
Dec Alpha OSF 2.0 C compiler) reject empty files.  From Kaveh Ghazi.
