Subject: [PATCH] vmcore-dmesg: Define _GNU_SOURCE
|
||||
|
||||
loff_t is guarded with _GNU_SOURCE on some C library implementations
|
||||
e.g. musl since this type is not defined by POSIX. Define _GNU_SOURCE to
|
||||
include this define, it should help compiling on musl while nothing
|
||||
changes for glibc based systems since there _GNU_SOURCE is already
|
||||
defined
