Agreed, at least while no package manager is used. 
I believe the most direct link would be this one:
	https://sourceforge.net/projects/mingw-w64/files/

Yes. DPDK config/meson.build now links with pthread if linker is not link.exe.

Note that maybe this can be relaxed (test needed!), i. e. link with pthread
if it is found, otherwise use shim. Benefit, if this works: no runtime
dependency on "libwinpthread-1.dll" for Windows.
