I'm trying to compile iperf3 3.6 under MSYS2.
./configure (autoconf) reports "checking for SetProcessAffinityMask... yes"
, but at compile time I get following related error
iperf_api.c:67:10: fatal error: Windows.h: No such file or directory
#include <Windows.h>
I do not understand how it is possible that during ./configure tests it can detect the presence of SetProcessAffinityMask and during compile is unable.
