Subject: stdio-common: Fix %m sprintf test output for GNU/Hurd
X-Git-Tag: glibc-2.35~204
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=422e4cd0ffbd71456cbefcf8027c866638c7124f;p=thirdparty%2Fglibc.git

GNU/Hurd has slightly different error messages for undefined numbers,
due to the notion of error subsystems.
