Subject: [dpdk-dev] [PATCH v2 2/5] build: increase readability via shortcut variables
Date: Tue,  9 Apr 2019 11:55:36 +0100	[thread overview]
Message-ID: <20190409105539.61460-3-bruce.richardson@intel.com> (raw)
Message-ID: <20190409105536.pR2NROnfG38rbhe6kn8AaGmi-svjLNzFtFQGYB_otGo@z> (raw)
In-Reply-To: <20190409105539.61460-1-bruce.richardson@intel.com>

Define variables for "is_linux", "is_freebsd" and "is_windows"
to make the code shorter for comparisons and more readable.
