Subject: logind: Fix compilation without ACL
X-Git-Tag: v30~29
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=2fb1aedaf2493d9598693c123d5e9c168ca1b3c1;hp=-c

logind: Fix compilation without ACL

Compilation fails if sys/acl.h is not available. The configure script
already tests for sys/acl.h presence, but the result was so far unused.
To compile without acl, stub implementations of the acl functions are
used.
