Subject: cmake: detect suseconds_t using CHECK_TYPE_SIZE
X-Git-Tag: v17.1.0~2082^2~7
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=731ec948315b34d1c8f63bfa0dd41911e63cd8bf;p=ceph.git

cmake: detect suseconds_t using CHECK_TYPE_SIZE

instead assuming it's a macro use CHECK_TYPE_SIZE to check it.

on Darwin, it's defined as `__darwin_suseconds_t`
