This patch doesn't work on macOS as expected. For example, https://travis-ci.org/shinnya/liberasurecode/jobs/564306690 (removes all cache before this build).

It seems .travis.yml can't put these package declarations together, so repeats them multiple times.

gcc 4.8 と gcc 4.9 は何か目的が異なるのでしょうか。

gcc 4.8 か 4.9 のどちらかが Scientific Linux 7.2 で使われているのではないかと思いますが、どちらか分からないため両方入れてました。
macOS も XCode のバージョンをどれをメインで使っているのか分からないので、色々入ってます。
あまりにもビルド時間がかかりすぎるので、絞った方がよい気はしています。

なるほど。
ちなみに Scientific Linux 7 および Cent OS 7 は gcc 4.8 です。
This resolves #10. This PR doesn't become a solution to the root of the problem, so we should update
openstack/liberasurecodeto fix.
