Subject: eal/windows: improve compatibility networking headers
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=f40a74cfcf029a81569b7e8e99301c91cce832d6;p=dpdk.git

eal/windows: improve compatibility networking headers

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.
