Subject: header: Fix build error with old kernel headers
X-Git-Tag: v1.2.3~67
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=bb43546c7a3d535576b49f0a729761ba6a348892;p=alsa-lib.git

header: Fix build error with old kernel headers

Old development environment doesn't necessarily contain the headers
defining __kernel_long_t that is recently used for y2038 timespec
conditional.  Define it explicitly in such a case.
