Subject: (initialize_exit_failure): New inline function.
X-Git-Tag: v5.1.2~29
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=78ac13ca26739bdb46a6d0144f55d3870692944e;p=thirdparty%2Fcoreutils.git

(initialize_exit_failure): New inline function.
Include exitfail.h here, since we refer to exit_failure.
All callers changed to not include exitfail.h.

(EXIT_FAIL, EXIT_CANNOT_INVOKE, EXIT_ENOENT): New enum values.
