Hi William,

I applied your v2 patch and I did a native build on windows 10.

Thanks, will fix in v3.

However the output looks weird:
> C:\dpdk\build\examples>dpdk-helloworld.exe
> EAL: Detected 2 lcore(s)
> EAL: Detected 1 NUMA nodes
> hehello fllo frorom cm core 1

It looks like your stdout is unbuffered (default is line-buffered). What
terminal are you using (cmd, Power Shell, Terminal App, conemu, etc)?

C compiler for the host machine: cc (gcc 4.8.3 "cc (GCC) 4.8.3")

GCC 4.8.3 is quite outdated, MinGW-w64 ships GCC 8 nowadays. Do we need to
support it for Windows (I doubt MinGW-w64 does)?
