Subject: [dpdk-dev] [PATCH 5/7] eal/windows: improve compatibility networking headers
Date: Sun, 21 Jun 2020 00:05:08 +0300
Message-ID: <20200620210511.13134-6-dmitry.kozliuk@gmail.com> (raw)
In-Reply-To: <20200620210511.13134-1-dmitry.kozliuk@gmail.com>

Extend compatibility header system to support librte_cmdline.

pthread.h has to include windows.h, which exposes struct in_addr, etc.
conflicting with compatibility headers. WIN32_LEAN_AND_MEAN macro
is required to disable this behavior. Use rte_windows.h to define
WIN32_LEAN_AND_MEAN for pthread library.
