Issue with clang-tidy and mingw

Question

I dont know if this is the correct place to ask, but i am having some problems with clang-tidy and mingw on windows.

Everything is working fine compiling with gcc and checking with clang-tidy. Except once i add "unistd" (for sleep). In that case it still compiles and runs perfectly fine with gcc. But First clang-tidy does not find the relevant header files and if i explicity give them via -I it prints out these errors that i have not been able to get rid of:
