Subject: Skip d_type check on platforms that don't have it.
X-Git-Tag: V_10_1_P1~307
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=755c3d082e59e6884f28d30e6333a1444e9173d1;p=thirdparty%2Fopenssh-portable.git

Skip d_type check on platforms that don't have it.

On those, the subsequent stat() should catch the sockets.
