A pretty important warning from clang-cl:

src/contrib/ports/win32/sys_arch.c(457,28):  warning: cast between incompatible 
calling conventions
'cdecl' and 'stdcall'; calls through this pointer may abort at runtime 
    h = CreateThread(0, 0, (LPTHREAD_START_ROUTINE)sys_thread_function, new_thread, 0, 

src/contrib/ports/win32/sys_arch.c(425,1):  note: consider defining 
with the 'stdcall' calling convention sys_thread_function(void* arg)

Mixing stdcall with cdecl can be dangerous; maybe not in this case though?
