Subject: examples: Define _GNU_SOURCE for more examples
X-Git-Tag: v10.1.0-rc1~89
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=9ef6541cecde4ebc16bcfc9c5860006f0d8fb2a9;p=thirdparty%2Flibvirt.git

examples: Define _GNU_SOURCE for more examples

Some of our examples use GNU/Linux extensions functions/variables:

1) domtop.c uses usleep(3),
2) logging.c uses getopt(3).

Put _GNU_SOURCE definition at the top of corresponding files so
that users can just grab the code and compile it (in contrast
with the rest of the code where _GNU_SOURCE is declared in
meson-config.h).
