I'm not sure of the reason for this. I don't see anything like this in configure.ac
In include/c11/threads.h the cases are: 1) building for Windows -> threads_win32.h 2) HAVE_PTHREAD -> threads_posix.h 3) Not supported on this platform So not defining HAVE_PTHREAD for anything not Windows just means we can't build at all. When we are building for Windows, I'm not sure if dependency('threads') would ever find anything, or defining HAVE_PTHREAD has any effect, but avoid defining it there, just in case.
