I think having the choice between GCC and Clang for Windows is very cool.

When starting the Windows port, I asked the fundamental question of the
supported compilers. The answer was MinGW adds "non-standard" DLLs:

Now the question is to know which one is the easiest to use?
If I understand well, MinGW brings the missing parts we are trying
to add in the DPDK repository for compliance with POSIX libraries.
