This is effectively in Phobos 1 at least:
https://github.com/D-Programming-Language/phobos/blob/phobos-1.x/internal/gc/win32.d#L27

My guess is this code was written when DMD was Windows only.

According to the history which I guess Brad imported first to svn and
then to Git, the code goes back to phobos 0.1, when the GC was written
in C  ;)
