• File src/thread_winapi.m — part of check-in [5358e9ea6a] at 2019-08-01 20:14:35 on branch trunk — Split threading.[hm] into multiple files

  This allows the runtime to only link against the parts it needs, without
  pulling in unnecessary parts like thread spawning, TLS and conditions. (user: js, size: 1805) [annotate] [blame] [check-ins using]
