Subject: [LTP] [PATCH 06/31] sendfile: Use off64_t instead of __off64_t
In-Reply-To: <1452240711-51180-1-git-send-email-raj.khem@gmail.com>

__off64_t is specific to glibc where as off64_t is widely available
Add _GNU_SOURCE for off64_t defines from sys/types.h
Fixes
<command-line>:0:7: error: unknown type name 'off64_t'
sendfile02.c:97:18: note: in expansion of macro 'OFF_T'
