Subject: Provide compat shims for sys/{mount.h,statvfs.h).
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3e9c4ed3b0e5d3890fcd2cbc9c3b595f17ea1946;p=thirdparty%2Fopenssh-portable.git

Provide compat shims for sys/{mount.h,statvfs.h).

In addition to shimming on platforms that don't have them, we also need to
shim sys/mount.h on DragonFlyBSD since it uses its native STAILQ_ENTRYs
which our compat queues.h does not have, which causes sftp-server.o to
not build.  This is a little icky, but it limits the blast radius to
just one source file on only DragonFly.  ok djm@
